Nothing to Lose

I liked this book written by Lee Child. The intrepid hero Jack Reacher travels back and forth between two Colorado towns, Hope and Despair. When he arrives in Despair for breakfast at a diner, he is immediately attacked and thrown in jail. Upon release he partners with a cop in Hope. Why is the small town with its mysterious metal processing plant and nearby military checkpoint so desperate to keep strangers out?

This is the twelfth book in the series. The book has several similarities to David Morrell's 1972 novel, First Blood.
