I decided to read this book after seeing the author and book featured on a recent episode of ABC's "20/20." The pace is fairly slow and kept my interest just enough for me to keep going. I didn't like or dislike it - I rate it a "push." I liked the author's writing style; …more content was somewhat lacking. The story had untapped potential. I was hoping for more. (less)

I echo many of the review on this website...the beginning of the story has potential, then dies on the vine. I was extremely disappointed with the book.

Although I'm not a huge Dan Brown fan, at least his books have good pacing to them. "Rule of Four" just meanders around …more most of the time without any real purpose. For all the authors wordiness trying to establish and build-up the characters, I never really cared for any of them. I felt little if any emotion for the characters or story itself. Very disappointing. (less)
