If you've ever liked 24, this is that. Jack Bauer, sorry I mean Reacher, is an ex-MP conveniently arriving in an otherwise anonymous frozen little town suddenly hit with some unexplained goings on that you just know are going to have some wider, and probably sinister, explanation. That only Jack can find out. If the authorities will let him. Etc.
Again, like 24, the story is time-bound. Although 61 rather than 24 - I guess it's got room for just over two and a half times more action! That said, it's a good read. A well written, if formulaic, thriller.
