All the set up was necessary to understand the final action, and was interesting from a very clinical point of view. I'm used to more emotion in the books I read, but obviously for this genre you just can't. Not for every character. I did, however, tear up at the end for something that happened to Mike, and I was definitely on edge for the climax of the story.
This is not my usual genre, so I don't know how it compares to other books, but I can say I enjoyed this one quite a lot.
There were a few technical errors in the text that I couldn't help but flag, but none that really grabbed me and took me too far out of the story.
Well done, Lee Duffy.
