Bellatrix Lestrange & her sister Annalee Black

Bellatrix has a problem. One that only a few people can know about. She goes to her twin with this secret, bringing Annalee back into a world that she had left long ago. She would do anything for her sister, even the thing that she dreads most: Becoming a servant of Lord Voldemort. Rated T because I wasn't sure in the later chapters.
