Rise of the Fourth Marauder

Peter had always been told that he didn't amount to much, and after a time, he started to believe it himself. Now, in his fifth year at Hogwarts, the shocking intervention of a higher power teaches him otherwise, inspiring him to alter the tragic path of his own fate. This effort pits him against the insane Lord Voldemort in a war to the death. AU, AntiHeroic!Peter, M for a reason.
