I liked this book more than their other book "Holy Blood, Holy Grail." The authors tell the history of the Knights Templar and the Freemasons while addressing the possibility of them being related. What I liked best about this book was the history, especially about the Revolutionary War. The authors really didn't pick a side, but they did leave the door open for you to belive about the possibility of a Masonic influence during the Revolutionary war. I'm not sure if I believe any of it, but it was an interesting theory.
