The Diamond Bridge

After her mother dies, a young woman discovers that she was abducted when she was two years old.  Instead of being kidnapped, though, she may have been rescued, but from who or what? She comes to learn that her original birth parents were witches and she finds refuge in her parents' old coven house. She considers claiming a legacy that rightfully belongs to her, but she learns that her inheritance includes more than things of this world.
She wants to avenge her parents' death but before that, she must restore her lost occult powers. What she doesn't realize, however, is that to extract her revenge she must defeat a source of evil that has existed since the beginning of time.
