The only 'problem' I had was that there seemed to be a jump to the gangs, and Santeria (is that the word? lol) - for a short time it seemed disjointed, then it all started to come together.
I also loved Decker, and I'd like to see more stories involving him.
The beginning was gory, but in a good way. It wasn't going for the shock factor, like authors like Laymon.. they were well written, descriptive scenes.
