It's the best book I've read in a while, in apocalyptic genres.
I got it on my iPad, and it's a thoroughly amazing novel. I would have read it in one sitting, were it not for being so busy. I'm glad I got it on my iPad, because I would read a chapter at a time, any time I could; on the shitter, while riding passenger in a vehicle, waiting at the doctor, etc. Hell, I read it while at the bar at Buffalo Wild Wings, because there was only one other person at the bar at the time, and they weren't interesting or sociable at all. Any excuse to get some reading time, I was on it.
