Don't Let Go

 I used to think I didn't like mystery books but after reading Harlan Coben's Don't Let Go I think I have changed my mind. I could hardly put the book down even when I had other stuff to do. This story is about a peace officer living in the house he grew up in. He lives alone after the death  of his father. His twin brother died at age 18 with his girlfriend. They were hit by the train. He has always tried to find out what happened that night. He meets with various people in each chapter learning a little bit more. I never saw the ending coming.
