I didn't watch the movie because it looked lame. So if it was and you saw it, don't judge the book. Movie previews showed some completely off things so I didn't bother seeing it.
Percy Jackson is an 11 year old demi-god and discovers it when his teacher turns into a monster and tries to kill him. After he joins his place with all the other half gods Zeus' lightening bolt is stolen and he's the prime suspect.
The series follows with The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth, and The Last Olympian. Each series gets better and better. There are rumors of a new series based on the rise of the new oracle. So excited!
