This is the number one, bestselling title in this new spin-off series from Percy Jackson creator, Rick Riordan. Old enemies awaken as camp half-blood's new arrivals prepare for war. 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 practising archery with flaming arrows and explosives. But rumours 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?
