File:Fragmented Soul I See Fire - Harry Potter Fenrir Greyback

Description
Heavily based upon the Harry Potter fanfiction "Fragmented Soul" by BickyMonster and StrawberryGirl87. (http://archiveofourown.org/works/933554/chapters/1817205)

Story: Harry, stolen away by Severus and bitten by Greyback as a baby, now lives with his pack. Meanwhile, Voldemort used Ginny and the diary to return to his youthful form. But Dumbledore tortures and imprisons Severus, forcing Harry to help in the war, bringing him to Hogwarts and sending him down a path that he never wanted to walk.

(I would highly recommend reading it because there is just so much more to the story than I could ever fit into a description here)
