it took me several weeks to finish this book unlike all of the other Brad Thor books I read. It just didn't keep my interest long enough to keep reading. When I finally did finish the book the ending was a very big disappointment. It was like a scene from another book. I know it was a supposed to be a cliffhanger but I just don't care what happens. This may be my last Scot Harvath book. I really have enjoyed all of the other books. I did read all of them.
