Von Neumann’s War takes place in the near future. The war begins when Mars starts to change color and albedo. Self-replicating machines have invaded the solar system and Earth is next.
We get to follow a rather geeky story of a few scientists and an officer who saves the world. In my opinion the characterization in this book isn’t really up to John Ringo’s usual standards. The Big Idea with an interstellar war with self replicating machines is great. They could have made it more interesting. The geek factor, if you are into IT, is quite high, there is lots of internet/network jargon.
