I cannot say enough great things about this book! I read it from cover to cover in one day. The author grabs your attention from the very beginning, and takes you on a roller coaster ride right up until the very end. There were so many twists and turns in this book, and I did not see a single one of them coming. I think it is fair to say that by the end of this book, I was completely “mind blown.” I found myself extremely impressed with Blake Crouch and wondering how somebody’s mind could compose such an intricate and convoluted story. After reading Dark Matter, I would place it in my mind as one of the top 5 books I have ever read. Since reading, I have recommended to several others, some of whom had already read it, and shared the same sentiment. I really can’t say enough good things about this book and this author. I will be reading his others in the future.
