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 acidentally vaporized my maths teacher. That's when things really started 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. Can Percy find the lightning bolt before a fully fledged war of the gods erupts?
