Rolling In The Past

After the war leaves the wizarding world in ruins, Harry travels the world for a spell to send his soul back in time. At age 58, he succeeds and manages to send his soul back 50 years. Things will be different this time and he will save the lives of all the innocents. I know this has been done before, but this is my take on it. Rated M just in case (though story is not M so far)
