Have you read Reacher yet? If not this is a great introduction. If you have read Reacher then what are you waiting for? There's a new book out!
****Little bit of a spoiler*****
This one ends with a cliffhanger which is different then the other Reacher books. The other books tend to wrap up and then you pick up in a new city with the new story. This one leaves you wondering. Some interesting touches in this new story that set it apart from other ones.
Again - what are you waiting for? You know you want to read it. Just set aside some time because once you start you will want to keep reading. The 61 hour countdown makes this a fast one.
