The war drags on after Voldemort's defeat and the Order of the Phoenix is fighting a losing battle. When Harry is hit by yet another killing curse, he wakes up years in the past and in an alternate reality. As an unknown child in a foreign world, Harry has a chance to change the outcome of the war - while dealing with new magical talents, pureblood politics and Black family drama.
