Raised by a Black - a tragedy

It's gonna be a twisted origin story of a young witch, named Susanne. The sad, abusive story turns to a happy life, which turns to another tragedy. This idea came to me in a half-asleep state. The basics are already written, but it needs a lot more editing than I originally thought.

Basic informations:
What if Regulus Black survived the Inferi-lake and find an innocent little girl, who turns out to be a witch with a terrible background. At the same time the Black brothers meet up and bury the hatchet. What happens when Susanne's past come back and starts haunting the girl?

The idea and other characters are created by me. My plan is that the storyline will follow the books' story as much as possible, though there can be differences.

Hopefully you'll enjoy it, have a good reading!
