Jason wakes up on a school bus, clutching the hand of a girl he doesn’t even remember meeting. Suddenly, a fierce storm crashes around them, and strange creatures appear! Just when everything feels upside down, they’re whisked away to a place called Camp Half-Blood — but why is everyone talking about a missing camper and a mysterious curse?
