Considering this book was written by a man from a woman's point of view, and even in spite of it, this book was excellent. Beautifully scripted, powerful and unrelenting in its portrayal of a truly twisted psychopath and the games played with the main character and her department. The ending was a surprise - rare with thrillers, ironically - and tied up loose ends nicely. The main character is not perfect by any means, both physically and emotionally, but that is what makes her a memorable narrator. One of the best books I've read in a while.
