Percy Jackson and the Olympians Books in Order

Percy’s second college-recommendation quest arrives in the form of a house-sitting job for Hecate just before Halloween. Tasked with watching over her crumbling mansion and temperamental pets, he soon finds himself in the middle of a three-aspected goddess’s dangerous disagreement.

During his senior year, Percy learns he needs letters of recommendation from three gods to get into New Rome University. The first favor comes from Ganymede, whose missing magical chalice could destabilize Olympus, sending Percy, Annabeth, and Grover on a lower-stakes but very personal quest.

As Kronos’s army marches on Manhattan and the gods battle the monster Typhon across America, Percy leads the demigods and their allies in a last stand to defend Mount Olympus. The war forces him to face the Great Prophecy and choose what kind of hero he’ll be.

Strange new entrances reveal that Daedalus’s Labyrinth now runs beneath Camp Half-Blood. Percy, Annabeth, Grover, and Tyson venture inside the shifting maze to find its creator before Kronos’s forces do, racing against time to stop an invasion from underground.

After a rescue mission goes wrong, Annabeth is captured and the goddess Artemis disappears. Percy joins the Hunters of Artemis on a winter quest across America to find them both, confronting new monsters, an ominous prophecy, and the first signs of the Titan Kronos’s return.

When Camp Half-Blood’s magical borders begin to fail and Percy’s friend Grover disappears, Percy sails into the Sea of Monsters to find the Golden Fleece. Alongside Annabeth and his newly discovered half-brother Tyson, he faces treacherous seas, sirens, and an old enemy’s plot.

Twelve-year-old Percy Jackson discovers he is Poseidon’s son and the prime suspect in the theft of Zeus’s master bolt. To stop a war among the gods and save his mother, he and his friends undertake a cross-country quest filled with monsters and modernized myths.
