Note: Chapter 2 is all about Leo's return and how Percy takes things into his own hands to bring his friend back. Percy Jackson is sent to Hogwarts on a diplomatic mission to forge ties between the worlds of wizardy and mythology. Thanks Luckybird10

A Percy Jackson and Harry Potter Crossover Fanfic The war with Gaea is over, and the only plans Percy have are to spend time with Annabeth.

When Dumbledore discovers the grandsonson of voldemort, things start to get a little weird. He didn't mean for it to happen, it just did! Percy didn't want to be the grandson of another old cart who wanted to take over the world, it just happened. What happened when Percy goes to Hogwarts?

Percy Jackson/ Harry Potter Crossover. Percy's Voldemort's grandson, and he goes to Hogwarts. There, he meets the golden trio and his nose-less grandfather. He is NOT liking his mother's side of the family very much.

When Percy is summoned home from camp to see some weird people on his couch, let's just say he's confused. When he finds out that he has another evil relation, he's not happy. Well, off to Hogwarts. Harry is astounded. Voldemort- the lowlife scum of the wizarding world- has a grandson. Now Dumbledore wants him, Hermoine, and Ron to get him, and become friends. Harry must be crazy because he agrees to go. Set after PJO but before HoO ( I want him 15/16) and during OoTP Check out my other crossover: Percy Jackson - the New Hogwarts Teacher Cover created by @Emer28702000
