This was one of my Book of the Month selections. I usually pick the mystery and suspense genre, whatever the selections are! I do really enjoy this type of genre. Yet with the popularity of psychological suspense, not all books come through. This one does. I was second guessing everything throughout. It's one of those books that halfway through you're like what? It had me flipping back to the first pages again. You think you might know what motivates the characters but you really don't! Just from the title you may have ideas of what the book is about but you really don't. Having read lots of suspense it takes a lot to surprise me and this one did. I am looking forward to these two authors next collaboration!
