Executive Power by Vince Flynn

If you can take all the macho BS and look at it as funny, this is a pretty good book with a good plot line and interesting characters. The main character, Mitch Rapp, well I'll let the writing speak for itself - "he's a rugged man that other men just naturally folow", "the military personel in the war room listened to Rapp because he'd seen action, infact he'd probably killed more men then all of them combined" - and it never stops.
