Lee Child has steadily accrued one of the keenest groups of admirers for any contemporary thriller writer – and the reason is easy to discern. In such gritty and authoritative novels as Tripwire, Killing Floor and Die Trying, Child established his tough itinerant protagonist Jack Reacher as a key modern hero, with a taciturn, hard-boiled appeal that has not palled over many books....

The pre-last book about ex-military Jack Reacher by Lee Child. 
Two small towns in Colorado: Hope and Despair. Between them, nothing but twelve miles of empty road. Jack Reacher can't find a ride, so he walks. All he wants is a cup of coffee. What he gets are four redneck deputies who want to run him out of town.

The 9th book about Jack Reacher, written by Lee Child.
Six shots. Five dead. One heartland city thrown into terror. But within hours the cops have it solved. A slam-dunk case. Except for one thing. The accused man claims: You got the wrong guy. After that, all he’ll say is: Get Reacher for me. Jack Reacher lives off the grid. Lone righter of wrongs, irresistible to women. What could connect the ex-military cop to this obvious psychopath? 

Killing Floor is the first book of the Jack Reacher series by Lee Child. "All [Jack Reacher novels] are ripping yarns, but since this is the first, it seems the logical place to start...Killing Floor wins awards for Best Corrupt Southern Town in a Summer Novel and Best Exploding Warehouse." Stephen King, Entertainment Weekly

Ex-military policeman Jack Reacher is lying low in Key West, digging up swimming pools by hand. He is not at all pleased when a private detective starts asking questions about him. But when the detective, Costello, turns up dead with his fingertips sliced off, Reacher realizes it is time to move on.
