I suppose I'm in the minority in that I thought it was mediocre. The prose was a bit dry, and occasionally awkward, and too much happens "off-screen" or reads like an encyclopedia entry. The characters felt a bit shallow as well, perhaps as a consequence of fitting too many perspectives into a relatively short story, so a lot of the dramatic events just didn't land for me. And the call-signs...my god, the call-signs! At one point, an opening paragraph for one chapter is just a rapid fire reeling off of troopers and their nicknames. It was clunky as hell and really killed the flow.
Not to say that it was all bad. The action scenes feel very authentic and there was some passable intrigue. I just prefer a bit more nuance and character work.
