What do you do when one part of you just wants the love of a good man, but the other one craves the way cold steel feels between your fingers and the warmth of blood as it spills over your skin?

Joanna Michaels is a woman who has a checkered past. While growing up in a broken home, she quickly learned that she was not like everyone else. From the moment she killed her parents without batting an eye, to the first unsuspecting victim, she knew that she could never confide in anyone. Of course, that is unless she was going to kill them soon afterwards. When detective Jon Harrison is appointed to the case, he notices that all the clues point in the direction of Joanna but he can't prove anything unless he goes deep under cover and gets her to confide in him. However, does he forget exactly why he is there when he gets a little too close to her?
