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

Percy Jackson had to deal with a whole new thing with demigods, gods, and monsters. What happens when he gets pulled into another world with wizards and witches? How will he react when he finds out about his family on his mom's side?

Well what if Voldemort had a daughter called sally Riddle, but she was sorted into Ravenclaw, he declared her a disappointment to the Riddle name. He soon over looked that but what if she got married to a man she thought was a muggle but turned out to be a god of the sea, Poseidon. Just imagine if they had a son they named Percy Jackson, who was a well known demi god! What if they were told they needed to send Percy to Hogworts!

the war was over. his friends were safe. that's all Percy cared about. maybe he could get some peace and quiet for once. boy, was he wrong. Harry was exhausted. what he really needed was a nice vacation away from all the publicity. he never thought he'd get it, even though if it was to new York to find Perseus riddle, voldamorts grandson. join our heroes as two world's collide. will friendships be made, or hatreds blossomed? find out in this epic crossover! sorry guys I tried. I suck at descriptions. it probably sounds cheesy. but I don't want it to be. most stories like this have Harry hating Percy but growing to like him. this will be different. *evil laugh*

When Percy, Annabeth, Nico, and Thalia get assigned a quest to protect Harry Potter, they never expected it to be back in time and in a whole different world: a world of magic.

Another prophecy, another quest. Seven demigods enrol as students at the Hogwarts School of Witchcraft & Wizardry. They're hoping to help the wizards and witches defeat...well, they have no idea. The poor demigods get an overflow of homework and boredom (or not?) as they wait for something to happen. But the Titan and Giant War were not the last war for the demigods, and neither was the Second Wizarding War the last for the wizards...this is. - Cover made with Viria's art Highest ranks - 1 in demigods, 5 in hogwarts, 3 in percy jackson, 1 in annabeth chase, 1 in nico di angelo, 2 in leo valdez, 4 in crossover, 1 in percabeth, 19 in harry potter, 11 in pjo, 1 in hp
