Percy Jackson, like any teenager, has issues: on top of having ADHD, he also has to cope with an abusive stepfather and dysfunctional home life. When he realises that he is a demigod and his biological father is Poseidon, the sea god, he sets out to prevent all-out war between the Olympians after the lightning bolt of Zeus is stolen, and he is framed for it.
