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?

Most people get presents on their sixteenth birthday. I get a prophecy that could save or destroy the world. That's how it is when you're the son of Poseidon, God of the Sea. According to an ancient prophecy, bad things will happen when I turn sixteen — because I'm the one who gets to decide the fate of the entire world. But no pressure. This is the one where Kronos, Lord of the Titans, is beginning his attack on New York City, where Mount Olympus stands virtually unguarded. Oh, and the dreaded (and not to mention enormous) monster Typhon is also heading our way. So it's me and forty of my demigod friends versus untold evil...

Look, I didn't want to be a half-blood. I never asked to be the son of a Greek god. I was just a normal kid, going to school, playing basketball, skateboarding. The usual. Until I accidentally vaporized my maths teacher. That's when things started really going wrong. Now I spend my time fighting with swords, battling monsters with my friends and generally trying to stay alive. This is the one where Zeus, God of the Sky, thinks I've stolen his lightning bolt — and making Zeus angry is a very bad idea...
