The Enemy ( I read this first because it's a prequel)
The Hard Way
Bad Luck and Trouble
Nothing to Loose
Jack Reacher is an awesome character. I am thinking of casting him in an actor, but I can't think of any one who'd be perfect as him. For sure, that actor has to be tall.
Not sure if they're going to make this one into a movie yet, but I sure hope so. I just finished Running Blind, and will start Without Fail when my laundry piles up again. :)
