I was expecting this to be one of the many psychological thrillers that I have read. But this book is different to any have read before. The main difference is that it was the girlfriends ex who was the murderer but in fact he was a serial killer at all, so she went on a hunt to find out about the murders and eventually find the real killer. With a major twist right at the end. I really enjoyed this book and it only took me a couple of days to read. I found the characters and their relationships interesting and I couldn't stop reading to see who the real killer was and what really happened those ten years ago. I would definitely recommend this to those who enjoy psychological thrillers. It was great.
