Percy Jackson (Books)/Synopsis (2024)

Percy Jackson and the Olympians[]

The Lightning Thief[]

Yancy Academywas where Percy's troubles seem to start. He has only one friend at the school,Grover Underwood, whom is also Percy's best friend. During a field trip to a museum, Percy is annoyed by the school bully,Nancy Bobofit, for intimidating Grover and in a fit of rage, accidentally summons water from a nearby fountain to pull her in, but he didn't know how he'd done it.Mrs. Dodds, his pre-algebra teacher, witnesses the whole scene and tells him to follow her into the museum for a "talk." Suddenly, she turns into theFuryAlecto, and attacks him, looking like a bat with humongous fangs. Percy manages to destroy her usingMr. Brunner's pen,Riptide, that transforms into a sword in his hand. However, when Percy returns to the bus and asks his classmates, nobody remembers Mrs. Dodds because of a force known as theMist. The only person that may remember her was Grover, who always hesitated before he answered. Everybody else believed her name was Mrs. Kerr.

Percy arrives back at the school and hears Grover and Mr. Brunner talking about his life being in danger and becomes very suspicious. At the bus stop, Grover sees that the three Fates are looking at Percy while knitting giant socks. Soon after, theFatessnip the string of life. Later, he goes home on his own at the end of the school year, even though Grover asked him to wait for him at the bus stop. He arrives home to his horrible step-dadGabe Uglianoand his friends playing poker. Gabe immediately demands money for his poker game and although Percy denies he has any, Gabe deduces that he has change from the cab drive and forces it from him. Percy's mother arrives soon afterward and tells him that they can go to his favorite beach inMontaukfor the whole weekend. Percy, happy that finally something good has happened, packs his things and leaves, but not before seeing Gabe get hit in the butt by the door when he does a weird hand gesture he sawGroveruse . During their night in Montauk, Percy had a vivid dream . The dream features two animals, which is a horse and a bird attacking each other. At the same time, there is a voice(that Percy describe as so deep and evil that it turned his blood to ice)gorging the two animals on. Percy was awoken by the pounding of the door . He and his mother are shocked to see Grover outside their cabin, without pants (which Percy recommends not to see that) coming to him and his mom, telling them to leave. Percy was confused at his friend's appearance, as he was a goat from the waist down and revealed himself to be asatyr. Nevertheless, his mother took them both in Gabe's prized possession, a 1978 Camaro and began driving at daring speeds through a blinding hurricane, and it was blasted off the road by a bolt of lightning. As Grover, Percy, and his mom tried to get out, they saw theMinotaur, a half man, half bull monster, who had been chasing them. The three of them managed to dodge it by following Ms. Jackson's advice to jump out of the way at the last second, but Grover was too slow and the Minotaur injured him, but got distracted by Percy's mother. The Minotaur forgot Grover, grabbed Percy's mom by her neck, and she disappeared in a golden flash of light. Percy, in a surge of new power and anger, managed to defeat the Minotaur by breaking off itshornand stabbing the Minotaur in the chest. Percy dragged the unconscious Grover past a hill, and then passed out when he reached the porch of ahouse. He was cared for in the infirmary byAnnabeth Chase, waking up three days later. He learned that he was atCamp Half-Blood, a place where people were trained to survive against monsters.

Percy learned that the director of the camp was the Greek wine god,Dionysus, who was very unpleasant and moody, and Mr. Brunner, former Latin teacher from Yancy Academy, was actually the hero-trainingcentaur(half human, half stallion),Chiron. Shown around camp by Annabeth, his new friend and head counselor of theAthena Cabin, he found out that all the campers weredemigods, also known as half-bloods. He himself was a demigod, but no one knew his divine father. After being shown around the camp, he currently resided in theHermescabin, whose head counselor wasLuke Castellan. Luke befriended Percy and treated him with respect. Afterwards, Percy encounteredClarisse La Rue, counselor of theAres' cabin, who performed the "initiation ceremony", which was sticking Percy's head in the girl's bathroom toilet. Her plan backfired when Percy shot water out of the toilet to blast back at Clarisse and her buddies. This officially began their rivalry. Later in a game ofCapture the Flag, Percy defeated Clarisse and three others single-handed when he touched the creek, which healed his wounds from the fight and gave him a sudden burst of adrenaline. After Capture the Flag, ahellhoundsummoned from theFields of Punishment, came out of the forest and attacked him. Percy's injury from the hellhound heals by touching the water; then suddenly,a holographic tridentfloated above Percy's head, which told everyone that he was the son ofPoseidon, the god of the sea, therefore explaining his powers over water. As the monster was not from the forest, it meant that someone within camp had summoned it, because nothing, including weather, could enter the camp's magic boundaries without permission.

One day, Percy was offered a quest to retrieveZeus'sMaster Boltby Chiron. Chiron explained to Percy that Zeus lost his master bolt, and (since Zeus has a rivalry with Poseidon) blames Percy, as Zeus suspects that Poseidon is attempting to dethrone him. Chiron said that if Zeus doesn't get his bolt back by that summer solstice, he would begin war with Poseidon. Percy accepts the quest and consults the camp'sOracle of Delphi. Soon after learning that Master Bolt has been stolen, Percy embarks a quest with his swordAnaklusmos, better known asRiptide, and Grover and Annabeth. Along the way, they face many monsters—the Furies,Medusa,Echidna, along with her petChimera. AfterAresoffers them a mode of transportation west, they arrive in Los Vegas, where they stumble upon theLotus Hotel and Casino. They get trapped in the casino for five days, leaving them only one day to complete their quest. They facedProcrustesbefore finding their way to theUnderworld. The trio faceHades, the lord of the dead, who believes Percy stole hisHelm of Darknessand the Master Bolt. Hades saved Percy's mother right before she died from the Minotaur, explaining the golden flash. Torn between saving his mom and finishing the quest, Percy finally usesPoseidon's Pearlsto find the missing gods' items. Immediately returning from the Underworld, he finds out that the war god Ares has the Master Bolt and the Helm of Darkness, and challenges the god to a duel for possession of the bolt and the helmet, in which he wins. A dark force, later revealed to beKronos, stops Ares from killing Percy. Ares vanishes in his divine form, leaving the bolt and Helm of Darkness behind. Percy gives the helm to the Furies to return it to Hades, who in return sends back Sally to her apartment, and the trio goes to New York to return the bolt to Zeus. Percy gives Medusa's head to Sally, who uses it to turn Gabe into a statue.

Percy goes back to Camp Half-Blood, where everyone at the camp congratulates him, Annabeth and Grover included. At the end of the summer, Percy can't decide whether to stay at camp or enroll in seventh grade and live with his mom. He finally decides to go train to clear his mind, where he sees Luke training at swordplay. As they drink co*ke together in the forest, Luke reveals he was behind the theft of the bolt and the Helm of Darkness, and vanishes. However, before he left, he summons a pit scorpion to kill Percy. Percy manages to kill it, but it stabs its stinger into Percy's palm. He tried to reach the camp but collapses. However, several forest nymphs carry him and after being fed ambrosia and nectar, Percy heals and decides to enroll in the seventh grade and come back to camp next summer.

The Sea of Monsters[]

When Percy is attacked byLaistrygonian Giantsat school, Annabeth rescues him along withTyson. On the way to camp, in theGray Sisters' Taxi, which is a taxi business run by the Fates. Percy learns some coordinates (the coordinates on where to find theGolden Fleece) that lead to something he needs. Percy arrives at camp to find the camp under attack byColchis Bullsand drives them back with help from Tyson who is fireproof. He later learnsThalia's pine treeis poisoned, meaning the borders are weakened and the activities director Chiron has been blamed.Clarisse, the daughter of Ares and Percy's enemy, is assigned a quest to go to theSea of Monsters(using the coordinates Percy received) to find and retrieve the Golden Fleece, which has healing powers for plants, animals, and humans which they need to heal Thalia's tree. Percy and Annabeth decide to go also, but Dionysus andTantalus, the new camp director replacing Chiron, refused.

Meanwhile, Polyphemus, a Cyclopes, captures Grover. Polyphemus believes that Grover is a female Cyclopes and he wants to "marry" Grover, for he is wearing a bridal gown. In desperation,Grovercreates anempathy linkwith Percy so he can call for help. With Hermes' help, Percy, Annabeth and Tyson board thePrincess Andromeda, the ship Luke and his forces are on and escape. They fight theHydraand get on Clarisse's ship, theCSS Birmingham. TheCSS Birminghamis a tribute to Ares. As they enter the Sea of Monsters, Clarisse, Tyson, Percy, and Annabeth have to get pastScyllaandCharybdis. Scylla lives on a cliff, while Charybdis lives in the middle of the entrance to the Sea of Monsters. Instead of attempting to sail in between the sisters, Clarisse automatically goes for Charybdis and Tyson, a good Cyclops and the half-brother of Percy, supposedly perishes in Clarisse's ship after the ship got blown up due to malfunction problems.

Percy and Annabeth journeyed to many dangerous islands including theSirens' IslandandCirce's Island, and Annabeth tells Percy several stories aboutThalia’s death, which she also mentions her prophecy. When they reachPolyphemus's island they join up with Clarisse,Grover, and laterTyson, who miraculously survived thanks toRainbow, a friendly hippocampi who dragged him out of the water. They leave with theGolden Fleeceafter fighting Polyphemus, which Polyphemus stole many years ago. When they return to the mortal world, they send off Clarisse on an airplane to the camp alone to drape the Fleece on the tree, and Luke kidnaps Percy, Annabeth, and Tyson, but Percy reveals Chiron's innocence in a secretIris messagesent to camp. Percy challenges Luke to a duel, but - with Percy being inexperienced and out of practice, which made him no match for Luke's polished swordsmanship - Luke effortlessly defeats him and very nearly kills him. However, Chiron comes to rescue them with his strangely dressedrelatives. When they return to camp, the fleece is placed on the tree, which not only revives it, but also brings Thalia back to her full life form. This revival was actually Kronos' plan, done so that he would have another chance to manipulate the prophecy that governs the future ofOlympusand theOlympians.

The Titan's Curse[]

Thalia Grace, Percy andAnnabethheard fromGroverthat twohalf-bloodsiblings,BiancaandNico di Angelo, had been found in a middle school. The three immediately set out to find him. Grover had been awaiting for their appearance. He explained that he found the two half-bloods and that they were enjoying a function in the gym. He was very nervous and embarrassed as the only person he could dance with was Annabeth, who had recently grown taller than him so he looked quite stupid "dancing" with her. Percy, having been forced to dance to blend in with the crowd sees the two half-bloods followingDr. Thorn, which was not a very good sign. Percy felt disgusted by the fact that Thalia was always powerful and a hero at everything she'd done and so thought it was now his time to shine and ran to save the di Angelo's from danger alone, though his plan did not work out as planned.

Then,Artemisand herHuntersappear and Annabeth falls from a cliff as she had climbed on Dr. Thorn with her knife before the Hunters shot him down with their arrows. Being a son ofPoseidon, Percy did not feel Annabeth dropping into the water, which confirms the fact that she had been captured. The Hunters saved Percy and his friends from the manticore. After a while, Percy clearly understood that he and Thalia were not under speaking terms due to the fact that Annabeth had fallen down the cliff. Nico had taken a great interest on the fact that he was a demigod and exchanged many thoughts on the Greek gods, Bianca had been dumbfounded and was summoned by Artemis with Percy, where Bianca pledged her life to Artemis much to Percy's protests.

Artemis then sends her Hunters to Camp Half-Blood withApollo, her twin brother. When he got to camp, Percy had frequent dreams about Annabeth and that she was in distress. He even went to see theOracle, however she didn't answer his questions and he left theatticin anger.

After a few days, the camp had aCapture the Flaggame, where the Hunters were up against the campers. Thalia and Percy agreed to be co-captains of the demigod team whileZoë Nightshadelead the Hunters. During the game, he learned from Grover that Zoë had a bad dream about Artemis being in trouble, while Percy himself had a dream that Annabeth was suffering under the weight of some unseen object. Thalia told Percy to stay on defense to guard the flag, but when he saw that her team was about to be attacked, he ran up the middle and took the flag. On his way back, he saw Zoë running back with his team's flag and was tripped up by an arrow two feet from the line, allowing the Hunters to win.

Thalia then runs up to Percy, asking him what he was thinking as when she got to the flag spot, it was gone. She thenshockshim, but claims it was an accident. Percy uses thecreek waterto splash her and claims that it was also an accident. Thalia and Percy begin to fight, each one summoning stronger attacks until Percy stopped, seeing the Oracle walking towards them. Percy simply watched as the Oracle approached Zoë, who asked about saving Artemis. The Oracle replied with a prophecy, saying:

Five shall go west to the goddess in chains, One shall be lost in the land without rain, The bane of Olympus shows the trail, Campers and Hunters combined prevail, The Titan's curse must one withstand, And one shall perish by a parent's hand'

Chironthen holds a meeting to decide who will go on thequest. Zoë originally wanted to take all Hunters, but she is convinced to allow a few campers as it was in the prophecy. Zoë however doesn't pick Percy because he is a boy, as Zoe thinks it's horrible to be with a boy, instead pickingThaliaandGrover, as well as her own Hunters,Bianca di AngeloandPhoebe. Percy was mad that he was not allowed to take part in the quest, since it was his chance to save Annabeth. That night, he is awoken byBlackjack, who tells him asea creatureis in trouble. He swims out and finds the sea cow trapped in a net and frees it slowly because it was scared of hissword, forcing him to free it by hand. On his way back to camp, he sees Nico spying on theArtemis' Cabinand usesAnnabeth's capto follow him. Percy overheard Zoe telling Bianca that Phoebe had been poisoned bycentaur bloodon a shirt thatConnorandTravis Stollhad given her earlier. Revealing himself to Nico, he is forced to promise Nico that he will watch out for his sister after Nico correctly guesses that Percy will follow the group on their quest. Nico leaves and Percy had just enough time to turn invisible before the Hunters leave the cabin, with Zoë almost bumping into Percy on her way out. As they leave, Percy followed them from above on hispegasi, Blackjack. They followed the car that the four traveled in and stops hours later when the group arrives at the Air and Space Museum inWashington, D.C..Percy then spots Dr. Thorn, the manticore, and overhears him saying that Annabeth is alive and that his dreams were true. He follows the manticore when it doesn't follow the group into the museum. He soon finds theGeneraland Luke, and sees the General creating severalSpartusthat he was going to use to kill and Bianca. However, the Spartus got hold of parts of Percy's sleeve instead of the General's piece of cloth with the Hunters' scent on it, resulting in them hunting him instead. Percy quickly escapes using Annabeth's Yankee cap to find the others. Zoë in particular, was surprised and angry when they realize that he had followed them and they were soon attacked by aNemean Lionthe Spartus close behind. After finding the lion's weakness, Percy helps defeat it by filling the monster's mouth with astronaut food he found in the gift shop. This made the monster expose his mouth long enough for Zoë to finish it off with an arrow.

The lion left behind aSpoil of War, itspelt, which Zoë gave to Percy as he had come up with the plan even though she dealt the finishing arrow. She also allowed him to join the quest after realizing that he is the fifth quest member, despite the fact that the Spartus, now disguised as gray security men thanks to theMist, are tracking him. They fled Washington and made it to atrain line, where they jumped into a rail car with a homeless man who offered them his fire. Though at first oblivious to the identity of the homeless land, a very bad haiku reveals him to be Apollo. He asked Percy to save his sister by looking forNereus, the Old Man of the Sea, as he could tell them where to find Artemis. Later that night, Percy has a dream where, unbeknownst to him, he isHercules, and is being handed Anaklusmos by a girl who later realizes is Zoë. Apollo takes them as far west as far as he could, to the last stop in a small town in New Mexico. Despite there being no real way out of the town, they tried to think of ways to leave including renting a cab.

However, theSkeleton Warriorsmanaged to find them again and attacked with handguns while Grover passes out asPan's presence overcomes him. As they tried to defend themselves against the undead soldiers, who would reform when killed, Grover senses Pan's presence again, along with a gift from the wild - theErymanthian Boar. However, because it is wild it attacks everyone, not only defeating the skeleton warriors and Thalia and Percy lead it into the woods. They are cornered at a cliff and he tells Thalia to jump at the last second. Thalia however is scared of heights, which Percy quickly figured out and pushed her out of the way causing the boar to crash into the snow.

Grover managed to use his nature magic to make an apple appear in front of the monster's face and the group ride it to ajunkyardinGila Claw, Arizona, owned byHephaestus. They camp there for the night, but a limo appears and Percy's blood began to boil, which meant Ares was nearby. The god of war came out of the car and told Percy to get inside, as someone wanted to talk to him. Percy reluctantly does so and findsAphroditeinside. She asks him to hold a mirror as she fixes some microscopic flaw on her face. As Percy watches her, she seemed to change into all the girls he had ever had a crush on. Aphrodite begins to talk about tragic love stories and eventually asked Percy why he was on the quest. He originally told her it was to save Artemis, but with some pushing by the love goddess, he admits that he is really there to save Annabeth. Aphrodite thrills at his response and tells him that she will make his love life very interesting, hinting that Annabeth and Percy will most likely have a romantic future together. She then sends him back to his friends and warns him not to take anything from herhusband’s junkyard.

While passing through, Bianca took aMythomagicgame piece ofHadesfor her brother, Nico. Because of the slight mistake, a defectiveautomatoncame to life and started attacking the group. Percy notices a manhole cover at the bottom of the machine's foot and was planning to enter it, however Bianca went in instead, sacrificing herself to kill the monster and save her friends. Percy and everyone else tried saving her, but they knew that it was completely useless as Grover announces tearfully that the next line of the prophecy has been fulfilled.

Thalia takes a truck and drives them to a river, where they rent a few canoes and Percy convinces a fewNaiadsto steer them to the Hoover Dam. When the Naiads start messing with him and Zoë, she tells him that they have never forgiven her. When they near the dam, Percy, along with Thalia and Grover, begin sprouting facts about the Dam, indicating the depth of their relationship with Annabeth is as the Hoover Dam was one of her personal favorites. They also makedamjokes about theDam Snack Barand the Dam Restroom, though Zoë was lost on the humor. As they go to get food, Percy hears the sound of asea creaturehe had befriended earlier. He tells it to go away and wonders how it followed him, but is distracted by the sight of remaining Skeleton Warriors - Bianca had managed to kill one in New Mexico.

He runs into an elevator to escape them, but then becomes trapped deep inside the dam. A tour guide, who turns out to be Athena, tells him that there is always a way out for those that are smart enough to find them, before ascending in the elevator. He is spooked when agirlappears behind him and he swings at her withRiptide, but the sword simply passes through her as she is a regularmortal. She then reveals she isn't so regular, as she sees the Skeleton Warriors for what they truly are and directs them away from Percy, who hid in a bathroom. As he thanks her, he introduces himself as Percy and that he has to go (which Rachel thinks means his name isPercy Gotta-go).

Up top, he warns the others of the danger and they are cornered at the top of the dam. He tells Thalia to pray to herfather, but she doesn't think he will answer. He says that Athena thinks he will and Thalia asked her father for help. Two statues come to life and swat the undead skeletons away before flying the group to California. There, Zoë Nightshade, who knows a lot aboutNereus, tells Percy to look for him by smell as it isdifferent. Percy finds him and hangs on for dear life as the old man tried to shake him off. Percy tricks him into going into the sea, which makes Percy stronger. Nereus changes into many animals to shake Percy off, but his attempts fails and he eventually agreed to answer their question. Percy asked what the terrible monster that Artemis was hunting was, which Nereus says is easy and points to the water before escaping. Percy feels tricked until Bessie, the sea creature that had been following him, appears in the water. Grover understands it and they quickly learn it is theOphiotaurus, the monster Artemis had been seeking as burning its entrails will give the person who does the power to destroy Olympus.

Just then,Dr. Thornappears with a small force of mortals and attacked the group, wanting to make his own place in theTitan Army. He tried to convince Thalia to slay and burn the Ophiotaurus so that she could destroy Olympus but Percy manages to shake her out of her stupor. When they were cornered, Percy sends anIris Messageto Camp Half-Blood, but finds onlyDionysuson the other line. Mr. D makes Percy ask him politely for help, which Percy does between clenched teeth, and the god saves them by wrapping the manticore and his men in grape vines, saving their lives. Percy then sacrifices the Nemean Lion's pelt to Poseidon to ensure safe passage for Grover and Bessie back to Camp Half-Blood.

Percy then goes to see Annabeth's father,Frederick Chase, as he may have a car they could use to save his daughter. After meeting Annabeth's family, he is shocked that they are so much different from the way Annabeth had described them, as to him they only seem caring and loving. Mr. Chase wants to save his daughter personally, but is told it is too dangerous for him, being just a regular mortal. He reluctantly agrees and gives them his car. Before they leave, Percy makes a promise to Mrs. Chase to tell Annabeth that she still has a home there with them.

As they drive up the mountain towards theGarden of the Hesperides, the car explodes due to a lightning bolt that struck it forcing them to complete the rest of the climb on foot. When they reach the Garden, Percy and Thalia finds out that Zoë is aHesperideafter meeting her sisters, and she is poisoned by the dragon,Ladon. Then they continue on to the place whereAtlasheld up the sky, though they find Artemis holding that burden instead. Percy finds Annabeth bound and gagged by Luke and the General, who is actually Atlas. Percy challenged Atlas, but his sword becomes too heavy, as Ares curse had finally taken hold (Ares promised that his sword would fail him when he needed it most when Percy won against him before). They were thrown into battle where Luke and Thalia fight each other, while Percy tries his best to hold off Atlas. In the ensuing fight, Percy saw the ruins ofMount Othrys, rival capital ofMount Olympusand home of theTitans, rebuilding itself. He realizes that this meant that the Titans' chances of victory are increasing.

Zoë then intervenes, fighting her father, disappointed with what her father had done. Percy used that moment to ask Artemis to give him the sky as he realized that the prophecy had involved him, and that only Artemis could have a chance against Atlas. He took it while Zoë and Artemis attacked Atlas together, but Zoë is hit and thrown against the wall. Artemis managed to push him back under the sky while Percy rolled out of the way. Sadly, Zoë began to die as Percy ran up to her during her last moments. She tells him that he is nothing likeHerculesand she is proud he carries the weapon she made before dying.

Percy rescued Annabeth and they manage to escape the mountain, thanks in part toFrederick Chaseshooting the monsters with his plane usingCelestial Bronzebullets. He, along with Annabeth and Thalia, then go to Mount Olympus on Blackjack and his friends,GuidoandPorkpie. While flying, Percy and Thalia believes that Luke is dead as Thalia had thrown him down a deep chasm, but Annabeth believes otherwise. Percy becomes slightly jealous with the affection Annabeth was showing for Luke, which surprises him because it have never really bothered him before now.

When they arrive in Mount Olympus, thewinter solsticemeeting had already begun, and they begged Zeus to believe thatKronoswas indeed rising. Thalia then chose to be an lieutenant with Artemis to replace Zoë, before giving Percy a hug. When he said she wasn't allowed to do that anymore (as Hunters can't become attached to males), she says she was merely honoring a friend. The gods then voted if they should kill Percy as he is the only known child of the Big Three to reach sixteen for theGreat Prophecyin two years. Fortunately many of the gods vote to let him live after Artemis declares that if he is killed, then the gods are no better than the Titans. Poseidon also vouches to let the Ophiotaurus live, although kept in Mount Olympus so it wouldn't be a "bargaining chip" against the other gods. Before Percy leaves Olympus, Poseidon tells Percy in private that he has done well and he is proud of him.

Back at camp, Percy tells Nico that his sister had died and gives him the Mythomagic figurine of Hades that Bianca meant to give to Nico. However, Nico blames Percy for not protecting her and throws the figurine away, telling him he hates Percy. At that moment, four of the Spartus appear, somehow managing to get past theCamp Borders. Nico thinks that they are for him and unintentionally splits the earth to swallow them and send them to the Underworld before fleeing into theforest. Percy, realizing that Nico is a child of Hades after the incident, tries finding him, but to no avail. While discussing Nico's abilities with Annabeth, Grover appears, claiming that he'd heard Pan's voice in his head. The three then promise to keep it a secret as Percy knows that Nico could also be a child of theGreat Prophecy, but instead says that he himself will take the responsibility of the prophecy instead.

The Battle of the Labyrinth[]

Percy Jackson thinks that freshmen orientation won't be fun, so his mother shows him the bright sides ("Tomorrow, you're off to camp! After orientation, you've got your date"). Orientation turns out to be hosted byempousai. When he is accompanied by a mortal acquaintance,Rachel Elizabeth Dare(which Percy thought she lived at Hoover Dam), who he met atHoover DaminThe Titan's Curse, she tells Percy to leave the room when she spots the demon cheerleaders that Percy had encountered when he went in through the side of the building to ignore Rachel. As Percy leaves, he ends up having to fight the empousai and runs into Annabeth along the way. They were supposed to see a movie together, but Annabeth is upset when she sees Rachel with him because she is jealous to see Percy hanging out with her when they were clearly supposed to be at the theaters. Annabeth takes Percy to Camp Half-Blood, a camp just for demigods like them. Percy finds his half-brother Cyclops, Tyson, cleaning their cabin.Quintus, the new swordsman, is accompanied byMrs. O'Leary, a hellhound that develops a soft spot for Percy.

During a game that Quintus made up, Annabeth and Percy go through the rocks ofZeus's Fistand fall in a dark cavern which they later find out is an entrance to the Labyrinth. Annabeth is offered the quest she has been waiting for since age 7: She must enter theLabyrinth, findDaedalus, and getAriadne's Stringbefore their arch enemy,Luke Castellan, does. Luke has been planning on burning downCamp Half-Blood, and is trying to use the Labyrinth to get there, guided by Ariadne's String. As Annabeth goes inside to get her prophecy, Percy waited outside and felt a little worried when Annabeth didn't come back for a long time. When she returns, Annabeth begins to tell everyone what the Oracle had told her, but she doesn't say the last line saying she doesn't remember. This strikes Percy as strange that she would forget something so important and begins to wonder what the last line could be. Annabeth takes Percy,Grover, andTysonalong with her. Together, they enter the maze. They are joined byHerafor a short time. She tells them that Percy knows the way, but Percy doesn't know what she means by that. When they take a wrong turn throughout the maze they run intoNico, son of Hades, at the Triple G. Ranch. Nico is accompanied byKing Minos's ghost, who tries to convince Nico that they are not his friends. Once they get out without Nico, Percy and the others run into a quiz show run by aSphinx.

After they escape from the Sphinx, they find an exit that takes them toHephaestus, who has them travel to one of his forges to find out who has been using them and in return, he will help them find Daedalus. Percy gets lost in the inner depths ofMount Saint Helenswhile battling fiercewater demons. Before parting with Annabeth, she kisses him for luck. Percy faces four full grown telekhines. They attempt to burn him with lava, but Percy, being a son of Poseidon, is hard to burn. In desperation, he unleashes an incredible amount of power and blasts out of Mt. Saint Helens, creating an explosion that damages the volcano, stirsTyphonin his sleep, and causes the evacuation of hundreds of thousands of people living around Mt. Saint Helens. He ends up falling intoOgygia, where he meetsCalypso, a young girl whom Percy thinks is much prettier than Aphrodite herself. Percy must leave the island and Calypso (who has fallen in love with him) behind. Calypso lets him use a magic raft that will take him to any place he wants, and the only place he can think of is Camp Half-Blood.

He returns to the shores of the camp and finds the camp strangely empty, except the amphitheater where everyone has gathered. As it turns out, they were getting ready to burn his shroud. Annabeth took the stage to say her final words, stating "He was probably the bravest friend I've ever had. He..." She then suddenly saw him and starts hugging him fiercely until she realizes she was making a big scene in front of all of the other campers. As they talk about plans to navigate the labyrinth, Percy realized he knew the answer after talking with Hephaestus on Ogygia; they need a mortal with clear sight to guide them. Once they are accompanied by Rachel, they run into a wide arena, where Percy battles adracaenaeand the demigodEthan Nakumura. Sparing Ethan, Percy challenges his giant half-brother,Antaeus, the arena master, that is accompanying Luke so that Luke's army can pass. Percy kills him by luring him off the ground, as his mother isGaeameaning he is invincible on the ground.

When he finds Annabeth and Rachel again, Rachel leads them straight to Daedalus' workshop, who tells them that he is Daedalus and the name Quintus was only a cover; and he also reveals that they are too late; Luke got there first and took Ariadne's string. He says that Rachel is better and more accurate than the string. Monsters then attack the workshop, dragging in Nico in chains. Percy, Rachel, Annabeth, and Nico escape and leave Daedalus and Mrs. O'Leary to fight the remaining monsters. They find another entrance and enter the maze once again. Once they navigate through the maze, Percy hears the Titan Lord speak to him. Taking Annabeth's invisibility cap, he goes into the room and opens the coffin. There, not fully formed, is Luke. As much as Percy hated him, Percy did not draw Riptide. He finds the demigod whom he spared earlier in the maze, Ethan. Ethan joins the Titan's side and Kronos comes to life in Luke's body. Percy barely escapes, thanks to Nico and Rachel (who had hit Kronos in the eye with a blue plastic hairbrush).

While they were going through the Labyrinth, they meet up with Tyson and Grover again. Together, they all findPan, the god of the wild, who tells them he is dying. As his spirit dies, it goes into the mouths of each of them except Nico, and it seems that Grover got a little bit more than the rest. Rachel leads them to New York, where pegasi take Percy, Annabeth, Grover, Nico and reluctantly, Tyson. The five of them had to leave Rachel behind, because she is full human. They go to help the camp ready for the Titan army's arrival. Battling side by side are Annabeth and Percy. Percy and Annabeth fight Kampê along withBriares's help. Grover, in a panic, screams so loudly that it scares the Titan army back into the Labyrinth. Grover's dryad girlfriend,Juniper, insists that it was Pan's wild scream that had scared the Titan army the first time. As Percy gets up, Daedalus comes and tells them that the Labyrinth is tied to his life. The child of Athena (Daedalus) dies, and so does the Labyrinth. Percy, Annabeth, and the other uninjured campers take the wounded to the Big House.

Percy decides to leave camp and go celebrate his birthday with his mom. Two surprising visitors stop by while Percy, Tyson, his mom, andPaul Blofis(Percy's mom's boyfriend and fiancée) are celebrating. First, Percy's fatherPoseidoncomes and tells him that he fears Luke/Kronos is only temporarily defeated and when Percy blew upMt. Saint Helens,Typhonstirred in his sleep. Finally departing withPoseidon, Percy decides to go to his room to plant the garden he had earlier promised Calypso. As he does, Nico stops by and tells him that he needs to tell Percy things about how they might be able to stop the Titan army. Percy then invites him for cake and ice cream.

The Last Olympian []

Percy is drivingPaul Blofis's Prius withRachel Elizabeth Dare, while on a quick vacation to the South Shore. Rachel is flirting her way into a relationship, Percy describes that he "felt like one of Apollo's sacred cows—slow, dumb, and bright red." They are soon interrupted byCharles Beckendorfand Blackjack landing on the hood of the car. Rachel briefly kisses Percy and Beckendorf makes a joke about not telling Annabeth about that little scene. Percy responds by saying, "Oh gods, don't even think about it." Then Beckendorf tells Percy that its time to initiate their plan to destroy thePrincess Andromeda, Luke's demon cruise ship inhabited byKronos's Army. While they are setting the bombs to blow up the ship, some telekhines attack. Percy distracts them to give Beckendorf time to arm the explosives. He battles Kronos, but Beckendorf is already captured. Because the explosives have no timer and Beckendorf has the detonator in his watch, he sacrifices himself to help Percy escape and carry out the plan and Percy jumps off the side of the ship and he loses consciousness.

In the water, he drifts to Poseidon's palace under the sea where he meetsTysonandotherrelatives. Poseidon is fightingOceanusand his army, aging rapidly due to the state of his kingdom being destroyed. Percy wants to stay and fight, but he must return to Camp Half-Blood to relay news of what happened on thePrincess Andromedato the campers.Chironand Annabeth agree to show him theGreat Prophecy, and after reading it he learns that his fate is to make an important choice and to have his soul reaped by a cursed blade. Percy is all keyed up for a while afterwards until a confrontation with Annabeth, when she calls him out as a coward. As he contemplates his fate,Nicoreturns to discuss the secret plan introduced inThe Battle of the Labyrinth. He wants Percy to bathe in theRiver Styxto become invulnerable like the heroAchilles. To do so, Percy Jackson must first discover howLukecould do it and they go visit his mother,May Castellanin Connecticut, where they find her insane and unstable. She does tell them that Luke came and asked her for her blessing for something that he needed to do. They also meet the goddess of the hearth,Hestia, who shows Percy visions of the destruction being caused byTyphon. Percy and Nico visit Sally and Paul back in the city, to get her blessing. She insists that Percy is now his own person, and that she has to let him go. Nico leads Percy to the Underworld, whereHadesreveals that it was all a trick to make Nico the child of the prophecy. Nico rescues Percy, though he seems to have lost his trust, and takes him to the Styx, where he is submerged in the water and becomes invulnerable, but for one tiny spot on his lower back.

The war begins and Percy leads the group of demigods into a sleeping Manhattan to battle monsters and demons, while the gods are battling the monstrousTyphonin the east. Rachel arrives, revealing that she has had a vision which read, "Perseus, you are not the hero. It will affect what you do." Ethan, aiming at Percy's Achilles Spot during a battle to invade New York City, stabs Annabeth in the arm with a poisoned blade. Annabeth had pushed herself in the way, as if she had a feeling that Percy was in danger. Percy is furious and horrified, knocking Ethan unconscious. Kronos threatens Percy to surrender or he will kill Annabeth, but Percy calls Blackjack who takes her to a hotel in a plaza. Annabeth is seriously injured, and Percy tells her where his Achilles spot is and that she saved his life. Annabeth remarks he looks "cute when worried" and that his eyebrows "get all scrunched up." When Kronos makes it to theHall of the Gods, Percy battles him to stop the destruction of the Olympians'Thrones. Kronos asks Ethan to kill Percy as he knows where his Achilles' spot is, however Percy convinces him that what he is doing is wrong. Ethan then charges Kronos, but Kronos opens up a fissure which causes Ethan to fall to his death. Annabeth is able to convince Luke to resurface. She reminds him of his promise that he would protect her, and asks Percy to give him theknifeso that he can end everything. Percy hands over the knife, discovering he was not the hero after all, but his choice to give it to Luke was the decision he had to make. Kronos is blown to dust and scattered by the wind, and Luke dies a hero's death.

Through deaths and betrayals, the demigods stand victorious. Percy is offered the gift of becoming a god, but declines due to his feelings for Annabeth Chase. He remembers how he felt when Annabeth might have become a Hunter of Artemis and notices Annabeth looks about the same way that he did then. Because of this, he declines their offer in favor of a request. He requests that the gods claim their children by the age of thirteen and that Camp Half-Blood construct cabins for Hades and the minor gods so their children have a place at camp. When he comes back to Camp Half-Blood, he finally expresses his feelings for Annabeth and they kiss twice, the first time in Camp Half-Blood's mess hall, and the second time being underwater, due to which a group of eavesdroppers toss them into the lake, the latter which he describes as 'pretty much the best underwater kiss of all time.' At the very end of the book, he and Annabeth share a moment of bliss as they race toward the road downHalf-Blood Hillback into the mortal world, not looking back atCamp Half-Bloodfor once.

The Heroes of Olympus[]

The Lost Hero []

Even though Percy does not appear in this book, it is revealed that he and Annabeth are officially dating. For most of the book, his location was unknown with the only clue being that he disappeared around the same time thatJason Grace, a son ofJupiter, first physically appeared. It is eventually revealed that Jason and Percy were exchanged byHera/Junoto unite the demigods of Greece and Rome againstGaeaand theGigantesand other creatures.

The Son of Neptune[]

Percy is being attacked by theGorgons,SthenoandEuryale, intent on avenging their sister,Medusa's, death. The sisters seemingly could not be killed as they reform every two hours while none of their attacks wound Percy because of theCurse of Achilles. He had been running from them for three days ever since they saw him. He had woken up at theWolf House, having no idea who he was or how he got there (and wondering why the Gorgons can't kill him), and metLupa, two months before the encounter with the Gorgons. The only thing he remembers is a dim memory of Annabeth. He believes what Lupa and the Gorgon sisters have told him about himself, that he is Percy Jackson, ademigod, the "son of a barnacle-encrusted god from five thousand years ago," which is Poseidon, whom they only know as Neptune. Percy then knocks out Stheno and uses her tray to slide down a hill.

He meets up withJuneand she gives him a choice: carry her to the other side of the road, or leave everything and go to the ocean, creating a new and invincible life for himself. Percy chooses to carry June to the camp, even though it means that he will lose the Curse of Achilles. After reaching the borders of the camp, he uses water from a nearby river to create two giant hands that destroy the sisters (as the water breaks their connection to the Earth). The waters of the river seemed to have also washed away hisCurse of Achilles, as after the waters receded, Percy felt like he had been in an acid bath and he felt vulnerable. Just then, Percy is met by many demigod children, includingFrank Zhang,Hazel Levesque, andReyna Avila Ramírez-Arellano. June introduces him as a son ofNeptuneand Reyna seems to know Percy somehow when she hears his name. June then shows her true form asJunoand the campers bow in respect, except for Percy who thinks that because he carried her all this way, he didn't feel that she deserved his respect.

Reyna then orders Hazel to take him inside where she could question him. Percy then meetsOctavianin theTemple of Jupiterand then meetsNico di Angelo, who he does not remember, but he does think that he knows him from somewhere. From then on, he is initiated into the Roman camp where he impresses some of the campers with his battle prowess during that nightsWar Games. At the end of the game,Marshimself appears and selects Frank, his son and Percy for the quest to free Death. Percy vaguely remembers his antagonism towards his Greek counterpart, Ares. He somewhat visualizes that they had a fight inin the past. They embark on their quest using the only vessel in the Roman Navy, a pathetic rowboat named thePax.

They sail to upper California where they meetIrisand see theGiant’s army. They then move to Portland where they encounterEllaand the wicked king,Phineaswho also appears to have knowledge of the past, present, and future although he is blind. Ella was wanted by Phineas as he thought she was a very preciousharpybecause of her knowledge. His intentions were to tie her up and keep her like that but the three friends find it cruel and make a bet with Phineas. They find the location ofThanatoswhen Percy gambles with Phineas using poison and healing Gorgon blood. By tricking Phineas, with Gaea's help, Percy is able to take the healing vial, from then on his memories begin to return. They eventually reach Seattle and the Amazon company which is run byHylla, Reyna's sister and also the former secretary ofCirce.

After escaping the Amazon compound with great difficulty, the group fled to Frank's house in Canada where his grandmother lived, who unfortunately “had an appointment with death” as the house burst into flames. She had told Frank that he was a descendant of Neptune and he could turn into anything. This had a great effect on Hazel as she was told byPlutothat she would be freed by her curse (blackouts about her pasts whenever she thought about them and finding cursed jewels wherever she was) by a descendant of Neptune. She had thought it was Percy but now she had no idea who would free her. Hazel had also kissed Percy on the cheek for his moral support. From there, they went to Alaska as more of Percy's memories returned. After arriving on the Hubbard Glacier, Frank was able to freeThanatosby burning a piece of wood which contained Frank's life. When the wood burned out Frank would die but only after Frank played a big role. He had entrusted his life with Hazel. Meanwhile, Percy fought off a legion of Roman undead warriors, using his powers to create a hurricane and a massive tidal wave. While Hazel, Frank, and Arion tried to kill Alcyoneus, Percy jabbed Riptide into the glacier. This caused several fissures to open up and all the undead soldiers and Percy himself went falling off the glacier into the sea below. After Frank and Hazel kill Alcyoneus, they retrieved Percy who had the Roman standard and was waiting on a block of ice for them to return.

They return to San Francisco on Hazel's horseArion, and by the time they return toCamp Jupiter, Percy had regained all of his memories. They metTyson,Ella, andMrs. O'Learyon the coast and arrived to the battle in the nick of time. Percy was able to slay the giantPolyboteswith the help of theRoman godof boundaries,Terminus. Terminus originally refused to help until Polybotes crossed the border with weapons (which was against the rules) and broke the statue of Terminus. This caused the god to become so angry that he agreed to help Percy, who used his broken head to destroy Polybotes by smashing his head with the head of the god. The other campers see this and raised Percy onto their shields and proclaimed him aPraetor. Later, he went to his room he had a dream and was visited byHeraand they argued about her stealing his memories and his life. During their talk, Hera warned Percy that Annabeth would be the one to cause the most trouble when he arrives in Rome. Percy enraged attempted to smash her in his dream, but she vanished and Percy`s dream ended. The next morning at the Senate, he explained to the Senate about Gaea, the Greeks and Romans coming together, and how the Greeks were on their way in a warship. Octavian tried to convince the Senate it was a trap, but Percy swore on his life that nothing bad would happen. When Reyna stood by Percy the decision was final they would hold fire. As theArgo IIapproached, Hazel explained to him the position he put himself in by swearing on his life, but nonchalantly Percy wraps his arm around Frank and Hazel`s necks and tells them to come and meet his other family.

The Mark of Athena[]

Percy is seen walking with Hazel and Frank as theArgo IIarrives atCamp Jupiter. Annabeth comes up with a plan to appease the Roman god of bordersTerminusand allow them to enter Camp Jupiter. Camp JupiterPraetorReyna, on advice from Percy, allows Annabeth, Piper and Jason to descend from their ship to have a meeting in the camp borders. Discussion over theProphecy of Sevenappears to go well and Reyna is on the verge of agreeing to co-operate. However, Leo, possessed by an eidolon, uses theArgo II's ballistics to fire at Camp Jupiter, causing a fight to break out between the two camps.

Jason, Annabeth, Percy, Hazel, Frank and Piper escape to their ship with the Romans hot on their tail. They begin their journey to the ancient lands, making a few necessary stops and visits to certain gods in the U.S before they can leave. After many obstacles, they get to Rome. In Rome, many more monsters attack, with the worst to come. When the demigods ofCamp Jupiterrealized that Rome was their destination, they resolved to instead go to war with Camp Half-Blood, and they march toward New York.

This, however, isn't their only problem. Annabeth, assigned a mission from her mother Athena to recover theAthena Parthenos, must go her own way and thus Percy becomes extremely worried. Furthermore, he still has to face his own problems, including drowning. After he battled with the twin giantsOtisandEphialtes(succeeding by working together with Jason andBacchus, the Roman form ofDionysus), Percy goes on to help Annabeth, even though a child of Athena must go alone. However, though he finds her in a workable situation that quickly changes.

Guarding the Athena Parthenos wasArachne, who Annabeth tricked into trapping herself. As Arachne falls into the abyss ofTartarus(she and theAthena Parthenoswere over the void of Tartarus), she shot out silk spider webs, one of which wrapped around Annabeth's ankle. Annabeth gets dragged towards to Tartarus, and Percy desperately holds onto her.

When it is clear that it was hopeless for Annabeth to be saved, Percy falls into the hole to Tartarus with Annabeth. The other demigods among theArgo IIare grief-stricken and fear the worst for Percy and Annabeth. Their fate is unknown as the moment, though Nico states if anyone can make it out of Tartarus alive, it's Percy. He then says then it's especially likely he will live because Annabeth is at his side.

The House of Hades[]

Percy and Annabeth have been falling for 9 days into Tartarus. They see the ground and a river rushing up to them, which Percy uses to catch them in their fall. The river was the riverCocytus, the River of Lamentation. It gave the two thoughts of giving up and drowning but Annabeth manages to get them to shore. The air in Tartarus is poisonous, and according to Annabeth, smells and tastes like styrofoam peanuts, which Percy remarks, smells like his stinky ex-stepfather,Gabe Ugliano. To enable them to survive the horrors of Tartarus, Percy and Annabeth drink from the flaming river, the riverPhlegethon, which allows monsters to endure the punishments in Tartarus. After drinking from the Phlegethon, Percy and Annabeth feel much better and are able to journey through Tartarus. They come across various reformed monsters and Titans, such asHyperion, and to their surprise, an old friend of Percy comes to help, the good-turned Titan,Iapetus. Iapetus, known as Bob, help them on their quest and allow them to find and close the Doors of Death. However, along the way, complications start to unfold asBobstarts to remember who he is. As they pass a golden bubble, in it the reformedHyperion, Percy asks Bob to burst his golden bubble since Bob is the only one with a weapon. They then come across thearai. Percy pleas with Bob for help, but Bob hesitates and allows him and Annabeth to get hurt because he realized that they were the ones who wiped his past memories. Seeing Annabeth in deep despair and blindness, Percy has no choice but to battle thearai, resulting in him getting the curse of slowly dissolving. This stretches back to the previous book,The Son of Neptune, where Percy had a bet withPhineas, resulting in Percy surviving after he prayed toGaea. Phineas then cursed Percy to die a painful death through dissolving. However, Bob finally decides to help after seeing who his true friends were. Together with Annabeth, he takes Percy to the giantDamasen's hut, to get him healed. With that, Percy is restored to his original health and the trio continue their journey to the Doors of Death. Percy and Annabeth use the Mansion of the Night to reach the Doors of Death. However, they are soon faced with great difficulty as the Death Mist fades and they can be seen by the hordes of monsters present at the Doors of Death. On top of that, the primordial of the pit,Tartarus, also takes on a physical form and begins his attacks on them. Percy intends to battle Tartarus, but is stopped by Annabeth, who feels that Tartarus is way too powerful and is a 'class by himself'. Bob and Damasen both agree with Annabeth. With much reluctance, Percy gets into the elevator with Annabeth and journey back into the mortal world, with a promise he makes to Bob to say 'hello' to the stars for him. Percy and Annabeth meet the other five demigods in Epirus and back on theArgo II, he fulfills his promise to Bob by looking in the starry sky and saying "Bob says hello", before theArgo IIcontinues sailing in the night.

The Blood of Olympus[]

After the group is informed that they must subdue the goddess Nike in the city of Olympia, Percy Jackson, Frank, Hazel and Leo decide to investigate, as their godly parents do not have any strong rivalry between them. They reach the site where the original statue of Zeus used to be there. Percy and Leo provoke Nike by remarking that Adidas shoes were much better than the Nike shoes. Nike, driven by her Greek/Roman schizophrenia orders a fight between the Greeks and the Romans. The demigods then hatch a plan to kidnap the goddess and start a mock fight. During the fight, Percy tells Leo, much to the latter's shock that he had discovered about his secret visit to Calypso, and promises to help him.

The demigods then fight Nike's servants, the Nikai, angering the goddess. She charges at Leo, but Percy quickly causes the water to explode beneath the chariot, smashing it and sending the goddess flying. Leo and Frank tie her up and take her to the ship. Afterwards, theArgo IIis caught in a hurricane and Jason and Percy go underwater to find out. There, they discover that the storm is being caused by the goddess, Kymopoleia, a daughter of Poseidon, who worked for Gaea. The giant Polybotes arrives and captures Percy in his net. Jason promises to honor the goddess. Kymopoleia accepts and decapitates Polybotes. After curing Percy, Kymopoleia warns him that he was yet to face his fatal flaw. Later, Percy, Annabeth and Piper sneak through the tunnels to Athens and attack the Giants. He and Annabeth are caught by the Giants. After they cut Annabeth's thigh, the rest of the seven attack. The assault goes well until Percy's nose bleed wakes the earth mother. Just then, the gods storm in and fight the Giants with the demigods. Percy and Poseidon fight Polydectis.

After the battle the seven learn that Gaea had risen at Camp Half-Blood. While thinking of a fast way back, Zeus suggests to slap theArgo IIback to Long Island which they agree on. The second they arrive at Camp Half-Blood, Percy fights off Octavian's recruits. When the battle is over Percy, Annabeth, Piper, Jason, Frank, Hazel and Nico meet at the Big House to talk about Leo. Frank and Hazel tell the others about Leo's plan. They are angry at first but calm down when the two cry while explaining it. Over the next few days the Greeks and Romans get along and he is present at the camp fire before the Romans head back to Camp Jupiter. Reyna and Frank then tell him that he and Annabeth can attend college and live in New Rome as long as they want. They soon tell Nico, who is happy for them. Nico then tells Percy that he had a crush on him, but is now over him, shocking Percy.

The Trials of Apollo[]

The Hidden Oracle[]

Apollo takesMeg McCaffreyto Percy's apartment because he thinks he can help them. When they arrive, he asked Apollo what he was doing here and was shocked to find out that he was not a god anymore. He invited the two in when they said they were being followed by malicious spirits.

Percy tells Apollo that he will take him and Meg toCamp Half-Blood, but he needs to focus on his school work as he promisedAnnabeththat they would attend New Rome University together and that he would also like to meet his younger half-sister. On the way to camp, the three of them are attacked by threeNosoi. One gets to Percy but he summons water from an underground pipe and washes it off of himself and Apollo before the disease becomes deadly, but becomes congested. He gestures for the fallen god to thank him, which he does. Percy tells the two to go to camp, while he talks to a police officer that has just arrived on the scene, and that he will visit the camp on the weekend.

DuringNero's attack on the camp, Percy andMrs. O'Learyarrive viaShadow Travel, and proceed to attack the huge Colossus, with Percy slicing off spikes from the automaton's crown and throwing them to the ground. He andChirondistract it, whileApollotakes it down with a plague arrow.

After the battle, Percy andRacheltalk with Apollo about what he is going to do next. After he tells them the prophecy he heard in theGrove of Dodona, Percy interprets that his help will be here momentarily, andLeo Valdezarrives shortly afterwards. While the rest of the camp both greets and hits Leo, Percy is so overjoyed, that he only hugs Leo, after which he proceeds to somewhat awkwardly greetCalypso. Percy heads back home soon afterwards, diving underwater withMrs. O'Leary.

Magnus Chase and the Gods of Asgard[]

The Ship of the Dead[]

Percy helps train Annabeth's cousin Magnus (who is also a demigod, but is Norse rather than Greek) by giving him an ocean survival lesson and tells Magnus of the possessiveness of sea gods over their weapons.
