I enjoyed this but for some reason it took me forever to read. It is a mixture of end of the world, vampire, epic fantasy. This is ultimately the tale of a band of people that survive 100 years after a devastating viral event. Yes, it was a military blunder (aren't most apocalyptic novels) that near destroys humanity and leaves the Earth plagued by vampire like creatures. It is not an original idea but it is written well. I would recommend it.
