Percy Jackson: Grandson of Voldemort
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
Another thing, but totally not relevant. Check out my other fanfic, Percy Jackson Meets the Electroclan.
