What if when our beloved hero Percy Jackson flees camp after being betrayed by the love of his life, he discovers that even his mother's family hides unknown secrets. With the discovery that Percy is actually the grandson of the infamous Voldemort, he is shipped off to Hogwarts, and there's just one question nobody in the Order of the Phoenix seems able to answer..... Can they trust him? Disclaimer: NO PERCABETH. I still ship it, I just wanted to try something different and if you aren't comfortable with that, please just don't read, I'm well aware that it goes against the core story but this is fan fiction, not cannon. Constructive criticism only please ❤❤.

I'm bad at summaries so please just try and read this. Percy Jackson goes up Hogwarts (hence the title) undercover and find out how it goes. This is only a short story so don't expect millions of chapters or anything. I made the cover, yay! (I do not get the point of these) I am not a middle aged man people. I am a teenage girl. I am not the author of these marvelous characters. I write FANfiction...and sometimes fiction but not in this story! The characters belong to the amazhang Rick Riordan and the wicked J. K. Rowling! This was my FIRST book, so if you read my other books you'll understand how this book isn't by best work, BTW

Annabeth Chase is your average junior at Goode High School. She gets straight A's, and you will never find her sitting in detention. Her best friend since kindergarten, Piper McLean, has always been there for her, since Annabeth's mother had died when she was six, leaving it to be just Annabeth and her father. Annabeth is just like everyone else. Just another face in the crowd. But what happens when she suddenly gets tangled up with Percy Jackson, the high school heartthrob? Percy Jackson is popular. His grades aren't great and he's had a few detentions in his high school career. He is known to be a bit of a troublemaker, in a lighthearted way. His best friend, Reyna (a bunch of names I dont remember) Arellano, is always at his side supporting him since kindergarten. Reyna was there when Percy's father walked out on him and his mother, Sally. She then got remarried to Gabe Ugliano, Percy's dangerous step-father. Percy faces the pressure of being popular, always in the limelight. He is able to keep cool on the outside to maintain his reputation, but on the inside, he's struggling with the stress. But when he runs into Annabeth Chase, his life is changed. For the better. What will happen to Annabeth? How is she so life altering to Percy? Find out in Who Could Have Known. I do not own any of the characters from the Percy Jackson and Heroes of Olympus series. They belong to Rick Riordan. And yes. I drew this cover myself. I know, I'm such an artist. However the idea was not originally mine. I copied it off google. So credit goes to the original picture, whoever made that.(idk tbh) Also, this is my first fanfic so be gentle and I apologize for any cringe/errors thank you FINISHED: 6/2/18

Voldemort is back and Percy, Thalia, and Nico are sent to Hogwarts to help with the war against the dark wizard. Will they be able to make it through the school year without revealing themselves? Placed after the giant war and in Harry's 5th year A/N: The writings kinda suckish in the first few chapters, stick with it, it gets better. Edited as of: 2/13/17

Kidnapped, separated, forced to save the world by condescending gods-Annabeth Chase and Percy Jackson don't need any more immortals on their doorstep, demanding the "please-clean-up-our-mess" service they never offered in the first place. But when Annabeth disappears from Camp-Half-Blood without a warning in late August, Chiron recruits Percy and his demigod companions to hunt her down. They soon find themselves posing as seventh-year exchange students at Hogwarts, and are introduced to a haunted British castle, a deadly Triwizard Tournament, and a boy named Harry Potter. With Hermione Granger determined to uncover Percy's real identity and Professor Dumbledore hell-bent on being as unhelpful as possible, the demigods struggle to navigate a world where everyone can use magic for better or for worse. Percy competes in the Triwizard Tournament with what is perceived as false hope to all his friends, and a belief that victory will lead him to his estranged girlfriend. But dark secrets are unraveled with each passing day, and the demigods all have their own battles to fight. Temptation, cowardice, PTSD and distrust gradually drive them further apart-will they ultimately defeat the sinister force that brought them to this deceit-ridden school? Because Harry Potter is not the only one with an unknown past, and Percy's own roots are tied to his enemy's 𝙧𝙚𝙖𝙡 motive.
