Time After Time

The war is lost. Everyone is either dead or dying. Hermione, fatally wounded, holds the only remaining knowledge that may give the Light a second chance. Using powerful but age old magic, she attempts to send herself back to before Tom Riddle was born. However, when she wakes up, she realizes she only managed to make it 20 years... the year of the Marauders. Alone, scared, and healing, she knows she has to do something. But what can she do, when everything she attempts could threaten not only the course of time, but her entire existence? And is she really powerful enough to do anything, especially when she finds herself befriending (and perhaps more) the very people that aren't supposed to know she exists?
