After the Giant war, Percy thought he'd settle into college with Annabeth in New Rome. But when he gets back from Camp, he finds six people in his house telling him he's a wizard. And not just any wizard, the grandson of the most evil wizard ever. Now he has to go to wizard school in Britain, which means missing his date with Annabeth and probably ending up in the middle of another war. But can he help the wizards? Or will they turn on him when they discover his secret?
