Percy Jackson and Annabeth Chase are normal demigods. At least, as normal as demigods get. Then they meet these shadowhunters and their life changes. Jace Herondale and Clary Fairchild are the best shadowhunters of their time. But then they meet the demigods and their life changes forever. This thrilling crossover consists of sass, romance and action.

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

Our favorite demigods as mortals in a average drama-filled world My old percabeth book was really bad and cringy and I wrote it 3 years ago, so I decided to rewrite it Hope you like it :D [And if you couldn't tell I'm really bad at summaries]

~Book Two in "The Demigod Selection" series~ "When you're in love, you will do anything to protect them. You'll lie, you'll fight, you'll steal, you'll kill. You'll become the villain just so they can survive. Even after they leave, you'll destroy yourself for their happiness" Prince Perseus Jackson had reached the time of his Selection. 35 girls were randomly Selected, making them a new part in the Prince's life.

Their saviors bring them to the D.I. and uncover a secret that no one had dared to even imagine. The Selection showed Annabeth Chase how far people will go for love. Love has brought her thus far. Will it be enough to safe her? ~Most characters belong to Rick Riordan, and the entire idea of a Selection belongs to Kiera Cass~

*READ TRUE LOVE FIRST Annabeth and I have been together for three years now. We've both left high school and are moving onto collage, both of us now living together. But our peace was about to be disturbed. After one fateful night, our lives both changed forever. We'll get over what happened. Maybe... I have no idea. We're Percy Jackson and Annabeth Chase, the ultimate pair when it comes to Monopoly. (Well, Annabeth is the one who actually plays, I just sit back and watch her take down Thalia and Rachel.) But even though we're the ultimate pair at Monopoly, for some reason I don't think that we'll survive this one unscathed.

I've never really thought about boys, to be honest. Me and Thalia swore that we would remain single forever, but now I'm not so sure. The first time I ever met Thalia's cousin Percy made me think he was a jerk, but it turns out I was wrong. After an architectural project involving his show at his dad's aquarium and a few conversations with him, I've realised that after all this time, I may like him - and more than just a friend. But here's the problem: my other best friend Rachel Dare likes him too, and I don't want to upset her, so what do I do? Lucky for me, I'm Annabeth Chase. And Annabeth Chase always has a plan. *A 2016 PJO Watty Awards third prize winner under AU section*

Percy Jackson has always been a troublemaker child. Ever since life dropped the Gabe-bomb on him. Fights, bad grades, suicidal thoughts. But then Annabeth Chase moves into the house across the street. A strong, clever girl his age. She was smart, independent, and, well, perfect. Let's just say that was just Annabeth's shell. Maybe she and Percy aren't so different.

But is what she's looking for worth knowing? An AU story about a mortal Annabeth and Percy. Read with caution, some gore scenes. Says completed, may make changes.
