Most of all, I love that nothing is a mere gimmick. The techno-magic system is original, fleshed out, and interesting. You rarely see that. There's a lot of pulp out there that manages one of the three, and good stuff that manages two, but nailing all three is rare. And this approach to deep, fresh ideas flows through every aspect of the book. Every little detail is weird and wonderful, and the implications of every detail are thoroughly explored. Nothing is window dressing here. Nothing is a gimmick.
This is essential reading for anyone who likes military sf. And I mean essential. It's an entirely new take on the genre, and you simply can't say you understand that genre if you haven't read it. In fact, if you haven't read it, I don't even want to be around you. Apart from how one-sided our conversation will be, as I gush on and on about this book while you stand mute, I'm a little worried that your unenlightened presence might destabilize the space around you. So read it.
