Where's Jack Reacher gone ? He appears to have turned into a vigilante killing machine over night. So many lines have been crossed that I fear for anyone on the wrong side of his moral code. I've read all his adventures to the point of having a sense of his character and if this was real you would have to ask yourself , has the guy finally lost his mind. I was hoping to read some kind of hope at the end but no it didn't happen . Please Lee Child think a bit before the next book sure don't mind waiting longer for it as long as there's some good old Jack back in it. Besides he must be getting on a bit now !!
