When Jason, Piper and Leo crash land at Camp Half-Blood, they have no idea what to expect. Apparently, this is the only safe place for children of the Greek Gods – despite the monsters roaming the woods and demigods practicing archery with flaming arrows and explosives.
But rumors of a terrible curse – and a missing hero – are flying around camp. It seems Jason, Piper, and Leo are the chosen ones to embark on a terrifying new quest, which they must complete by the winter solstice. In just four days time. Can the trio succeed on this deadly mission – and what must they sacrifice in order to survive?
