Percy Jackson and the Mirror of Erised [Book 1] by LindinCapps

Percy Jackson lost his mother at a young age. From then on he was stuck with his abusive step-father, Smelly Gabe. He didn't have much. Just one good friend. This friend was Harry Potter. One day, an owl pecked on Percy's window, and his life was changed. For the better or for the worse, he's not sure. That was the day Percy found out he was a wizard. Now, Percy finds himself a student at Hogwarts School of Witchcraft and Wizardry. He also finds that he's abnormal for wizard standards. Percy Jackson is a demigod. A powerful, illegal, demigod son of Poseidon. Follow Percy as he deals with magic, training, and three-headed dogs in his first year at Hogwarts.

The Wizarding War has ended and Percy is ready to start at Hogwarts as Deputy Headmaster. But the aftermath of the war is not quite what he hoped it would be. The Wizarding World is wary of Percy and unsure of how to handle the Greek Pantheon. And there is still lingering trauma and resentment of those who chose the wrong side... While Percy navigates his new job, his relationship with Hermione, and his mysteriously failing health, he cannot help but be reminded of his first five years at Hogwarts. Because Percy's learning that to move forward in the future, he needs to come to terms with his past. Before it kills him. (Essentially, this is both a prequel and finale to the Nexus series)

The Demigod Invasion (Percy Jackson and Harry Potter Crossover) by FluffyeEyeball

It was a month after the Second Titan War, and Percy, Nico, and Thalia are reluctantly being sent to Hogwarts School of Witchcraft and Wizardry on a quest. But, Percy would much rather spend it with his Wise Girl. Their job: protect Harry Potter. A seemingly easy quest, until Harry's name ends up in the Tri-Wizard Tournament. Now, they find themselves getting grey hairs, and losing sleep, as they try to keep us with the Wizarding World. In this crossover, they meet Ron, Harry, and Hermione as they try to navigate their fourth year and the Tri-Wizard Tournament. But what evil plans do they discover one Goddess has in mind? Read and find out.

Part 1 of the "Demigods...." Anthology. Demigods and Wizards. Two groups of supernatural ability. So similar, yet so different. Ever wondered, which one would come victorious in a battle to the death? Well, it happened. Their worlds collided head-on, erupting in a swirling inferno no one could have predicted. It was survival of the fittest, the most ruthless. Two sides entered the battlefield, but only one will walk out. Percy Jackson and Harry Potter knew this. And they were ready. To fight, and to kill. "Neither can live while the other survives." Let's see who won, shall we?

After fighting a bloody war with Gaea, the demigods at camp half blood get issued a prophecy asking them to bring back a son of Hecate who was mistakenly taken by the ministry of magic to be a wizard. Their time at Hogwarts is full packed as their presence in the magical world weakens the border of Gods and wizards and monsters follow them just the same. Just like always, they have been assigned an impossible task as the identity of the misplaced demigod comes to them as a shock.

Percy Jackson: Grandson of Voldemort by Poke_Master57

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

The war is over. The demigods can finally relax right? Wrong. The demigods discover the land of wizards to which they have been invited to. But what happens when the wizard try gain their help?

HECATE'S BLESSING ( Harry Potter x Percy Jackson) by black4diamonds
