Something's wrong with Alice

All magic, all witchcraft, depends on the Devil, and is fundamentally evil.
MONTAGUE SUMMERS, Witchcraft and Black Magic

In the Old Ages, witchcraft was considered a sin against God. You were the child of the Devil if you practiced witchcraft. And, you would be sentenced to death. Your blood would be burned, condemning the witch back to hell.
Emily Charlton, the fiancée of a professor, investigates the existence of witches. She never believed in the dark magic.
Then, she meets Alice Gray. An unusually blue eyed girl who likes to hide in the shadows. TO Emily, she seems normal. As normal as any ten year old girl.
But darkness can always hide behind the light.
