Night School - Lee Child

Night School is the 21st Jack Reacher novel. This one takes place while Reacher is still a major in the army.

Reacher just got his second Legion of Merit. Now it looks like he could be working on a third. He's pulled into some kind of joint mission with the FBI and the CIA. It's got terrorists and traitors and lots of other interesting players. Wait until you find out what everyone is trying to find. Very highly recommended. Lee Child never disappoints.
