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.

Percy Jackson is trying to be normal. He has tests to take, he has a girlfriend and friendships to keep up. He has a life, but of course the fates have other plans for him. Percy Jackson gets chased by some strange people in spandex, so what's he do? He ran, which seems to have been a mistake. Now the Avengers are looking for him and without knowing their intentions, Percy begins to question his choices. Then things just get worse from there!

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!***
