47 parts Complete 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 friends were two kids named Leo and V which was short for Vivian, 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 and. Then her best friend Vivian is a very powerful demigod. 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.
Vivian is a protector. After the Titian, when Chiron comes saying he has found 2 half-bloods, Vivian went with Coach Hedge. The three months that Vivian had with the 2 half-bloods, was amazing. But something terrible happens, her brother Percy has gone missing and she can't go and help find him. When a boy named Jason ends up an a Wilderness Field Trip, She, Jason, Piper and Leo, are sent on a quest to save the Queen of the Gods.
When secrets are revealed and truths are told, people realize that the next Great Prophecy has begun and a greater threat than the Titans are coming.
