Ancillary Justice is billed as Space Opera. I quite enjoy space opera.
I suppose it is space opera, from a certain angle, in the sense that there are spaceships, planetary invasions and shoot-outs on shuttlecraft. It felt like rather more than that, and the core of the plot is built around something else entirely.
Damn good.
