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.
