Hi Virginia,
I think I have read Vince Flynn's books, but don't remember Mitch Rapp. I will have to get a copy. BTW..I just picked up Christine Feehan, Murder Game, next book to read and she write about GhostWalker series. It's a romantic/suspense story and her last book about GhostWalkers was very good. Her books have the GhostWalker Creed and symbol details. Just a thought if you are interested.
