Since I love this movie, I had to read the book. I had a great time with this one! Would have to say that the only thing in common between the book and movie is that there is a character named Ben Richards and a Running Man game. I flew though this book in a day and a half jand would have to say the ending was perfect. I was a little lost with how much time had gone which each chapter, especially with the countdown chapters but understood closer to the end. I will be interesting to see how they remake the movie.
