The Camel Club Series is great for the mystery and political thriller lovers. I have liked almost everthing that David Baldacci has written. http://www.davidbaldacci.com/web/content/view/38/37/

Scot Harvath is a counter-terrorist operator who is a lot like Jack Bauer. http://www.bradthor.com/

And Mitch Rapp makes Jack Bauer look nice. I have liked every single book that Vince Flynn has written. http://www.vinceflynn.com/
