Rewrite Time

The war is over the death eaters won, Harry Potter is dead. The order of the phoenix was destroyed, almost everyone was killed. But Hermione escaped, to plan a new way to take down Voldemort. While trying to go back in time to the start of the final battle, an accident sends her all the way back to the marauder's era. Hermione creates a plan to save thousands of lives if she just does it right. She tells herself to not get too attached to anyone. But when she starts to fall for Sirius she realizes how hard that will be.
