If you don't know who Jack Reacher is, then read no further. If you do, you have probably already read most of the Reacher series except for "The Affair," which I grabbed from the library a week ago and returned today. Previous Reacher novels have been set in Georgia, Indiana, Texas, and Montana among other states.
This time the main setting is a small town next to an Army Ranger base in northeast Mississippi in 1997. The town sounds a little like Corinth. A railroad and a nightly train play a big part in the plot. The book explains, more or less, why Reacher the wandering ex-MP is the way he is.
There are the now familiar head butts, one-on-six fistfights, broken necks, shots to the head, sex scenes, and a few references to Reacher's brother and other characters who show up in other books. He only passes through Germantown and Memphis a couple of times, and the descriptions are minimal.
That's all I'm telling.
