Percy wakes up from a seven year sleep and finds out that Gaea has taken over the world. The seven did not defeat her. All demigods are scattered, in hiding, or taken captive at the Half-Blooded Jail. Percy vows to find all of his friends, especially Annabeth, free the Gods, and the world from Gaea's clutches. But how can he succeed when everyone thinks he's dead? (Post BoO)
