Percy Jackson and the Lightning Thief (Book 1)

Half boy. Half God. All Hero. 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. Now I spend my time battling monsters 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.
