Jason has a problem. He doesn''t remember anything before waking up on a school bus holding hands with a girl. Apparently she''s his girlfriend Piper, his best friend is a kid named Leo, and they''re all students in the Wilderness School, a boarding school for bad kids. Piper has a secret. Her father has been missing for three days, and her vivid nightmares reveal that he''s in terrible danger. Now her boyfriend doesn''t recognize her, and when a freak storm and strange creatures attack during a school field trip, she, Jason, and Leo are whisked away to someplace called Camp Half-Blood. Leo has a way with tools. His new cabin at Camp Half-Blood is filled with them. Seriously, the place beats Wilderness School hands down, with its weapons training, monsters, and fine-looking girls. Weirdest of all, his bunkmates insist they are all - including Leo - related to a god.
