An accident sends Hermione to a time where the war is approaching and where she has a chance to change more than one fate. The story begins at Easter, after the snatchers have caught our golden trio (Deathly Hallows CH 23: Malfoy Manor), and it is an Alternate universe from there. Some Hermione/Sirius, but Hermione/Regulus is endgame.
