If you are looking for a great thriller than I highly recommend any book written by Riley Sager. His stories completely take over you and hold onto you from the beginning until the very end. There are always twist and turns that have you guessing all the way through. I have enjoyed every book he has written and I look forward to the new books he will write. In order of my favorite, I would have the say that Final Girls was my favorite followed by Lock every Door and then The Last Time I Lied. These are some of the best thrillers I’ve read in a long time and I encourage you to read them as well.
