I have read Sum of All Fears and Clancy is one of my favorite authors. I think I have read all his novels with Jack Ryan. I have only read one Op Center book.
I hope they keep Kyle Mills writing the series. I have read all but a couple of the Mitch Rapp books. I am sure you will enjoy The Survivor.
Have you read “Term Limits” by Vince Flynn?
If not, I recommend it highly. We need “Term Limits” today.
