**UNDER EDITING** Upon being betrayed by all his friends and cheated on by his girlfriend, Percy Jackson flees from Camp Half-Blood, broken hearted with an unquenchable thirst calling for revenge. Antagonistic, broken and slightly on the brink of insanity, Percy sought out Hecate, the only goddess who was impartial to him. She offers to send him to a school she created, safe from the destruction of the Gods- but with a price. He had to grant her one wish in exchange, whenever she wanted it and if it was in his ability to do so. Left with nowhere else to go, nowhere else to run, Percy accepts Hecate's offer. Arriving at Hogwarts School of Witchcraft and Wizardry on the 1st September as a Seventh year in solitude, Percy Jackson takes upon a new identity, a chance to start afresh. Could Hogwarts help him back to glory, and succor the hero back to who he was before? There is no try anymore. There is only do.

Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne

Percy is constantly kicked out of school. He can't help it! Monsters find him but to mortals it looks like he's killing the pet hamster or catching the school on fire. His mom knows that the Greek gods move with the west. She figures monsters do the same and sends Percy to a new school in the east. Percy Jackson is now a foreign exchange student in Paris were he meets two unlikely people, Marinette and Adrien and uncovers their secret. Marinette on the other hand is dealing with a terrible situation. She can't choose between Adrien or Chat Noir! When she decides to reveal herself to him, things might get out of hand with the monsters Percy brought on accident. I don't own Percy Jackson and miraculous or any of its characters. I wish I did though😛 NOTICE: This was written in 2018 and I was 13. In other words, it is bad. There are typos, the writing is god awful, and I censored the hell out of it. If you read, I ask you not to point these things out because I genuinely do not care, I'm an adult, those comments are just annoying. I still think this is charmingly funny because of how bad it is, so don't let this warning deter you.
