The next chapter in the #1 New York Times bestselling Percy Jackson universe! Book 1 of The Heroes of Olympus fantasy adventure series for readers ages 10 and up.

Classmates Jason, Piper, and Leo learn they are actually demigods who must embark on a quest to rescue a certain missing deity...

This special edition includes exciting new cover art by graphic novelist Nilah Magruder.

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 3 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, prophesies, and quests will be left breathless--and ready to tear into the next chapter of Heroes of Olympus!
