Percy Jackson is about to get kicked out of school…again. He doesn’t mean to get in trouble, but it follows him everywhere and he just doesn’t know why. At least not until he finds out the teacher who’s always hated him is one of the Furies, and his friend Grover is actually a satyr, sent to protect him. Soon Percy discovers that all of his troubles happen because he’s the son of a Greek god, and he finds himself first surrounded by other half-human kids like him and then out on a dangerous quest to recover Zeus’s stolen lightning bolt. And if he fails, it means war among the Gods—and probably the end of the world as we know it.
