"Stumbling upon a murder is the biggest shock of Noah Holden's life - until he learns he knew the victim. When more women from his past are killed, Noah needs Officer Emily Walt's help to remove his name from the top of the list of prime suspects. But then the serial killer acquires a new target, they must work together before Emily become the next victim." This is a good book conceptually and the situations are promising but I found the book to be lacking in depth and evolution. Various scenes are shallow and thinly developed while others were rich and cerebral. ( )
