Overall Thoughts:
While I found this equally as enjoyable as the first two books in the trilogy, I ultimately felt that the answers to all the questions were less satisfying than the questions themselves. The worldbuilding surrounding these answers, centered on the extinct civilization that built the obelisks, Syl Anagist, is deep and imaginative, but it resolved all the sense of mystery and wonder present in the earlier books. The new setting, which feels more like science fiction, is also so different it almost feels like a different book. 

That said, the quality of the writing is superb and there is excellent character exploration throughout. I especially liked how thematic parallels were woven through the book, both in the past and present but also in Essun and Nassun's respective character arcs. The trilogy’s central themes of power, oppression, and intergenerational trauma are not only revisited but amplified, and Jemisin skillfully explores how these dynamics existed in the seeming utopia of Syl Anagist, just as they had been explored earlier in the Fulcrum and the Stillness. Essun and Nassun felt like two sides of the same coin, each pursuing similar yet diametrically opposed goals, leading to an inevitable confrontation as the story progresses. Themes of personal choice, and the difficulties in making them, also run parallel for all three characters (Essun, Nassun, and Hoa) and were quite strong.
