Jason has a problem. He doesn't remember anything before waking up in a bus full of kids on a field trip. Apparently he has a girlfriend named Piper and a best friend named Leo. They're all students at a boarding school for "bad kids." What did Jason do to end up here? And where is here, exactly?

Piper has a secret. Her father has been missing for three days, ever since she had that terrifying nightmare. Piper doesn't understand her dream, or why her boyfriend suddenly doesn't recognize her. When a freak storm hits, unleashing strange creatures and whisking her, Jason, and Leo away to someplace called Camp Half-Blood, she has a feeling she's going to find out.

Leo has a way with tools. When he sees his cabin at Camp Half-Blood, filled with power tools and machine parts, he feels right at home. But there's weird stuff, too--like the curse everyone keeps talking about. Weirdest of all, his bunkmates insist that each of them--including Leo--is related to a god.

Join new and old friends from Camp Half-Blood in this thrilling first book in The Heroes of Olympus series.
