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.
`` What he did to end up here, Jason has no idea--except that everything seems very wrong.
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.
What is going on? 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.
What's troubling is the curse everyone keeps talking about, and that a camper's gone missing.
Weirdest of all, his bunkmates insist they are all--including Leo--related to a god.
