Demigod Percy Jackson leads a quest across America to prevent a war among the Olympian gods.

Percy Jackson is on a dangerous quest. Outrunning monsters and outwitting gods, he must journey across America to return Zeus' master bolt and stop an all-out war. After losing his mother, Percy is sheltered at Camp Half-Blood, a sanctuary for demigod children. He must prove himself and confront his origins once he discovers he too is a demigod, and will take off into the perils of pursuing enemies in search of the Underworld. With the help of his quest mates Annabeth and Grover, Percy's journey will lead him closer to the answers he seeks: how to fit into a world where he feels out of place, if he'll ever see his mother again, and if he can ever find out who he's destined to be.
