Query: Lots of action!

I'm usually not a fan of science fiction books, but this one held my interest from the beginning, probably because it sticks to the story and keeps you guessing about what will happen next.The author's knowledge of military terms and procedures is obvious and makes the storyline ring true. The only thing I found myself wishing for more of in the story was romance, but that's just me!
