When Percy and Annabeth become gods, they expect to be left alone and not have to go on anymore quests, but oh no. As a favour to Hecate, the 2 go to Hogwarts with Will and Nico to learn more about the wizarding world. Whatever they expected, they didn't expect this. When Harry, Ron, and Hermione repeat their 7th year at Hogwarts, they expect a peaceful year for once. But what they get are 4 suspicious exchange students, strange monsters, and a big adventure.
