What an annoying mess. It wasn't horrible*, but it had no meat, no new developments, and it spun around in place. If they'd fought the war in this mindset they would've been crushed.
Only thing I did like some was Rainier in the beginning, and despite most of the book following him and Surreal, a character I really like, neither was ever fleshed out.
(edit months later: * Oh yes, yes it was. It was fucking awful. I don't know why I shied from shouting it. I'm still angry at the disservice done to the lead for the sake of turning a short story into a novel)
