Percy just wanted some peace and quiet. He finally defeated Gaia, the world is normal...but the fates, as usual, have a different idea. Percy, Annabeth, Jason, Piper, Thalia, Leo, Nico, Hazel, and Frank have to play bodyguard. For who, might you ask? Someone special. Someone who is going to need help, since his worst enemy has returned, bringing one of Percy's along for the ride. Who is this kid? Why, Harry Potter, of course! ***As you can tell, I don't own Harry Potter or Percy Jackson, props to those authors for actually coming up with the idea! I do have a few OCs but that's it!***

He'd finally found them. Tom Riddle's heir. A boy no older than seventeen, with hair of a raven night and eyes of a churning ocean. The wizened old man closed the weathered book. The Fates had been kind enough to let him in on this secret, one he fully intended to use to his advantage. The boy must not fall into the wrong hands. It was time to pay an old student a visit. ~ DISCLAIMER: I do not own either the Harry Potter characters nor the Percy Jackson characters used in this story.

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.

So, the demigods go to Hogwarts. Stuff happens. Yeah.

The order of the Phoenix asks the demigods in America for help to defeat Voldemort. Now Nico, Thalia, and Percy are going to Hogwarts to avoid being thrown into another war. Will they be friends or enemies with the golden trio? Will they be able to avoid the war or will they be at the center of it? And for which side will they fight? Disclaimer: I don't own Percy Jackson or Harry Potter. All rights go to Rick Riordan and J.K. Rowling. Except the plot. The plot is mine.

What happens when Camp Half-Blood and Hogwarts meet? Percy Jackson is asked to teach at Hogwarts as the new DADA teacher, but will he last as a professor? Voldemort is getting ready to kill Harry, and the war is coming up. Will the demigods ally themselves with the wizards? Or will they let their differences split them?

What if Percy, Annabeth and Thalia aren't just demigods. What if Percy's mum is a witch? What if Annabeth's Dad was a wizard? What if Thalia, though her mum is mortal, what if she is a witch? What happens when they go to Hogwarts and be friend the golden trio? Be prepared for a whole year of trouble, fun and secrets. I do not own Percy Jackson or the Heroes of Olympus. Rick Riordon does. I do not own Harry Potter. J.K. Rowling does
