This novel starts out as one thing and develops into something much more. At first you have an Escape From New York feel except much more realistic. In fact kudos to the author(s) for sitting down and thinking about how could something like this be done. Killadelphia has a great backstory that keeps you riveted and by the end I would say you can include a touch of sci-fi. The main character Cheo, I personally can't help but love. Certainly flawed like everybody he has an inner strength I really admire. His main asset is his brain which I also admire. The only problem is now I have to wait for book two. Highest Recommendation.
