An Angel For Mia

Harry Potter unknowingly stumbles fifty one years into the past, where he discovers an innocent girl with a past much like his own, and seemingly he is the only one able to help her overcome the trauma she had been living with for so many years. Can Harry be the savior of both worlds? The past and the present? Her world and his own? Or will one face destruction in the process? One man can only do so much. Even if that one man is The-Boy-Who-Lived. Very loosely based on the book and movie, An Angel for May. AU.
