This book was more a 4.5 rating for me. I was truly amazed by how suspenseful this book truly was, also how mysterious it was. I really like the fact that it would switch between Paul's (one of the main characters) past and present times. At first your thinking that he was one of the killers but then later on you find that he wasn't. Then like half way into it, your trying to figure out what friend was killed then your blindsided by a twist that I didn't see coming at all. They had other twist that shook me to my bone in this book as well but nothing like the finding out about the one friend/ kid was killed. This book is a true mystery and thriller book. The only thing that I could complain about is that the ending seemed rushed to me. I was hoping for a little more conclusion then what we actually gotten. But overall this book is extremely a great read. It is well written easy and quick to read. I truly recommend this book to all the fellow mystery/suspense lovers like me out there.
