All year the half-bloods have been preparing for battle against the Titans, knowing the odds of victory are grim. Kronos's army is stronger than ever, and with every god and half-blood he recruits, the evil Titan's power only grows. While the Olympians struggle to contain the rampaging monster Typhon, Kronos begins his advance on New York City, where Mount Olympus stands virtually unguarded. Now it's up to Percy Jackson and an army of young demigods...

Jason, Piper, and Leo, three students from a school for "bad kids," find themselves at Camp Half-Blood, where they learn that they are demigods and begin a quest to free Hera, who has been imprisoned by Mother Earth herself.

When domonic cheerleaders invade his high schook, Percy Jackson hurries to Campamento Mesitzo, from whence he and his demigod friends set out on a quest through the labyrinth, while the war between the Olympians and the evil Titan lord Cronos draws near.

After learning that he is the son of a mortal woman and the god of the sea, twelve-year-old Percy is sent to a summer camp for demigods like himself, and joins his new friends on a quest to prevent a war between the gods.

The demigods and their allies must defeat an army of giants in order to thwart Gaea's plans to have two of the demigods sacrificed in Athens, spilling the blood of Olympus that would help awaken her.

Greek and Roman demigods from the Prophecy of Seven must work together to seal the Doors of Death, and help Percy and Annabeth escape the Underworld in the process.

Percy Jackson and his new friends from Campamento Júpiter go on a quest to free Death while also working towards the fulfillment of the prophecy.

Demi-god Percy Jackson and his friends must journey into the Sea of Monsters to save their camp. But first Percy will discover a secret that makes him wonder whether being claimed as Poseidon's son is an honor or a cruel joke.

The formerly glorious god Apollo, cast down to Earth in punishment by Zeus, is now an awkward mortal teenager named Lester Papadopoulos. In order to regain his place on Mount Olympus, Lester must restore five Oracles that have gone dark. He has to achieve this impossible task without having any godly powers and while being duty bound to a confounding young daughter of Demeter named Meg.
