After the Giant War, Percy Jackson was never the same. The love of his life, along with many of his closest friends, was in the Underworld. He visited them frequently with Nico, and took breaks from being at camp, where memories of his love came to him everyday. Until something changes, and he is sent off to England because of dangers unknown to him. Harry Potter is having an awfully hard time going back to Hogwarts to redo his final year, along with the rest of the students who decided to return. With a new student who has secrets even Hermione can not puzzle out, strange attacks happening every couple of weeks, and a new approach on magic, the year isn't turning out as expected. It seems that Hogwarts can never fully be at peace.
