Essentially a re-telling of "The Seven Samurai", this is a good page-tuner. I'm glad to see the writer has several other books released, seemingly all in the same universe, so I'll be sure to look into those as well.
Self-publishing is great, because you can skip the traditional channels. Unfortunately, some of the process of traditional publishing is very useful. In this case, it would have been highly beneficial for the author to have this professionally proof-read prior to publishing.
Third, and thankfully, last in the series. Significantly less enjoyable than the earlier two. Our hero is now approaching self-deification, while his "girl" simply tells him "without you, none of this would be possible". Of course, being the last "civilized" people on earth, that would be true in any event.
If this was not the conclusion to the series, I would have stopped reading at least half-way through, but I really (really) wanted to see how it all ended, and had to grit my teeth for this one.
