Clever book with an interesting story that occasionally gets hidden under a plethora of acronyms. It is more intellectual than action oriented in many ways through most of the book but is intelligent and well written. We get to follow the process from discovery that our solar system is under invasion through the almost hopeless battle for survival against robotic invaders. As ususual there are off the wall fringe characters who come up with last minute saving answers. First in a series. I agree with the previous reviewer that most of the John Ringo is saved for the end and the majority of the book is Travis Taylor.
Very creative. The setting is now, but the technology is a nice mix of current, future and fiction. Even if the "bad guys" have better technology, we have either more gray matter or more cunning. And we have had centuries of experience in fighting for survival.
