One of those epic multi-generational spacers. This book has a lot going on, most of which I liked. However it does the same thing that Semiosis does where each chapter is some random amount of time in the future so I spent a lot of time trying to remember who was whom. Lots to unpack in terms of nature vs. nurture, class vs. actions & some pontificating on what might the planet be like if you came back to it after 2000 years. Will definitely read the sequel.
