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?
