NULL STATES by Malka Older

Reviewed over at Tor.com:

This is a story about governance and governing, about power and systems, and the edges of both—the parts where they break, and warp, and potentially break down. Older’s gift is to make those systems fascinating and human: relevant, and easy to grasp. Well, one of her gifts: she has great skill with evoking place and its complicated histories, when her characters stay in one location long enough.
