Death is but the Next Great Adventure

What if that night in Godric's Hollow went differently? What if Harry did die? What if Death stepped in and made a deal with the Savior of the Wizarding World? How different would Harry's life be after that deal? (Or, Harry makes a deal with Death and in exchange gains something Voldemort has fought his entire life for. Immortality. And a strange friendship with Death) (Harry/Tom)
