The Covenant's Blood

Lily realizes one thing the 31st October of 1981: Dumbledore can't protect them. She decides she can't get rid of Voldemort herself and needs her friends, all of them, to be united against the common enemy. For that, she digs in her power as a Dark Witch and rewinds time with James at her side.

Now that they've defeated Voldemort, Lily can rest and watches her son go through Hogwarts peacefully, like he was meant to be. Except he wasn't meant to do that, and now he's in Slytherin, he has a crush on a blonde boy who is the absolute worst, and Voldemort might not be that defeated after all.
