This is a difficult to categorize book. It is a mystery but with a dose of the supernatural. Just about every reader will think they have the story figured out when they are about 35% through the book. My question at that point was how could the author keep the rest of the story interesting. The answers are simple. The reader really didn't understand how the title pertained to the story and there is an unexpected twist.
All in all, an intriguing premise for the story that should keep just about any reader interested.
