Read the book. It was more about Kersh than the Legion of the Damn. Honestly I would like to see more of the Legion of the Damn but considering that they are more like specters and silent warriors I could see how hard it can be to write them as characters.
Overall the book was OK. The action was so-so and at times I found myself just speed reading waiting for the Legion of the Damn to appear. The story line was predictable to a degree . I mean you got the sense that this is their last stand with the Legion of the Damn coming to the rescue.
