American Football, Aliens and a unique universe designed by the king of Podcasting, Scott Sigler.
If you are interested in American football it will help your enjoyment of the book, but even though I am not a big fan of the sport, I still found it a good listen.
As with most Scott Sigler stories there is a lot of violence and bloodshed, and a little foul language, but I find that this gives the stories more of a gritty realism.
