A slightly non-typical Reacher: This story is a little more about Reacher's unfinished business as an MP than it is about his constant wanderings and accidental encounters with people in need of his unique brand of justice.
Though I have to say I couldn't help but think about Tom Cruise as Reacher as I read this one and it just did not gel well with me at all. Whatever it is that Lee Child and the movie producers are thinking, it's not rational.
