Rick Riordan

Camp Half-Blood is dying and Percy Jackson has to sail into a monster-infested sea to save it, all while untangling a family secret that complicates everything he thought he understood about being Poseidon's son. The second Percy Jackson book raises the stakes without losing the fun.

Percy Jackson just wants to survive sixth grade without getting expelled again, and instead finds out his gym teacher is a monster and his real father is a Greek god. Rick Riordan's series opener turns the Greek pantheon into a living, functioning world hiding in plain sight across modern America.
