Percy Jackson

by Rick Riordan

The Greek gods are real. They live on the 600th floor of the Empire State Building. And they have way too many kids. Percy Jackson discovers he's the son of Poseidon and gets drawn into a world of quests, prophecies, and monsters that want to eat him — all while trying not to get expelled from another school.
