I'm fascinated by ravens and crows, and the complicated mythology and symbology surrounding them. Even so, this story didn't resonate with me. Brenna was just so passive. Everyone around her was doing things to her, or for her, or at her - she was the absorber of the actions of others. Until the very end, when she finally made a decision and did something. I'm still not sure what she did, or what her decision was, or even what the question was. But at that point the narrative ceased to feel so oppressive, and ended well.
That and - like a previous poster, the repeated phrase "back and back and back" just made me think of chickens.
