Thana Archer thinks she knows what her life is about. A mid-level manager at a manufacturing company, Thana is good at what she does. She doesn't believe in magic, witches or ghosts, because those things just aren't real.

One day, a strange man appears with a strange box and an even stranger story about a family Thana has never known. After him there are others seeking to kill her because she is Thanatou, a Blood Witch. Trying to stay one step ahead of the would-be-assassins, she has to race against time to find the mother who abandoned her all those years ago.

To get to safety, Thana will have to sacrifice her freedom. But can she come to terms with the truth about her past, and the magical powers she doesn't yet understand?
