The Gun Counter

Holy cow. I finally saw an FB ad that made sense. It was for some book called 'Under A Graveyard Sky', Kindle edition on Amazon.
Good datamining there, FB. It's exactly the sort of book I enjoy. I know you don't know I already have it, in various formats, (including rough drafts) but it was a good job of matching a book to interests. Keep tweaking those algorithms and before you know it you'll be suggesting David Weber books, like, say, the Empire of Man series, or even Larry Correia's Monster Hunter International series.
