"Riordan extends the franchise in a logical direction while maximizing the elements that made the first series so popular: irreverent heroes, plenty of tension-filled moments fighting monsters, and authentic classical mythology mixed in with modern life."--Horn Book

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.

Fans of demigods, prophecies, and quests will be left breathless--and panting for Book Two.
