Godfather Death

In return for a favor, Death offers Harry a second chance. But Harry's second chance changes a lot of things about the world. All the Marauders live, and a Harry Potter grows up loved, but that isn't our Harry. He grows up in the middle of pureblood society as a completely different person, a child with the mindset of a war veteran. TimeTravel AU MoD!Harry (but not overpowered).
