I'm definitely already biased towards N.K. Jemisin, but this was a fantastic work of urban fantasy and speculative fiction. I believe the first chapter of this book was first published in her book of short stories (or it was revealed to me in a dream, because somehow I recognized it) but the full experience was incredible and so well written. This is one of those books that starts with a concept that makes you groan a little at how corny it might be, but then turns out to be incredibly clever in ways that keep making you stop and reconsider. Or hits you with the magic and scaling system that just click into place so perfectly it's like okay, every new development just makes SENSE. Thank you, I'll have another.
