One of the best books I have ever read. A fascinating world and it's development told across thousands of years parallel to a human story so vastly different and yet also the same all culminating in a tense disagreement that really tore me apart on who to route for and was resolved absolutely perfectly. I cannot recommend this book enough. Lovable characters, fascinating worldbuilding, high-concept sci-fi, mind-expanding perspectives and the weirdness of something so alien somehow made so human. I've never read a book so fast.
