The Sentinel (Jack Reacher #25) by Lee Child with Andrew Child

Jack Reacher gets off the bus in a sleepy no-name town outside Nashville, Tennessee. He plans to grab a cup of coffee and move right along.

Not going to happen.

The town has been shut down by a cyber attack. At the centre of it all, whether he likes it or not, is Rusty Rutherford. He's an average IT guy, but he knows more than he thinks.

As the bad guys move in on Rusty, Reacher moves in on them . . . 

And now Rusty knows he's protected, he's never going to leave the big man's side.

Reacher might just have to stick around and find out what the hell's gone wrong . . .and then put it right, like only he can.
