The Stone Sky is the third and final volume in N. K. Jemisin’s Broken Earth series, and brings it to a satisfying conclusion. I read this as an e-book, and while this wasn’t my favorite book by the author, I found it to be an intriguing series that finally brought the reader to an understanding of the strange world of the Stillness by the end.
The Stone Sky won the 2018 Hugo award for Best Novel, making Jemisin the first author to win this accolade in three consecutive years. Follow these links to find my reviews for the first book (The Fifth Season) and the second book (The Obelisk Gate).

This book begins immediately after the events in The Obelisk Gate, so it’s going to be hard to avoid spoilers if you aren’t caught up to that point. Read on at your own risk.
Essun has survived after activating the obelisk gate, but has found that she must now pay the same price as Alabaster when she uses orogeny at this point. Her body is being gradually transformed into stone. Each time this happens, she lets her stone-eater companion, Hoa, consume the inert flesh to relieve her of its weight.
Hoa features a greater part in this final book as he tells us of his origin. He was not always a stone-eater, but even in his previous form he had never been accepted as a normal part of society. Finally, we learn what happened in the distant past and how the world came to be the way it is.
The third part of this book follows Nassun, Essun’s daughter, as she comes to terms with her the ability to change the world and possibly end it for everyone. While her mother seeks to heal the world and repair the damage wrought by humans, Nassun sees salvation in complete destruction of humanity.
Once it is clear that mother and daughter have both similar but opposing goals, their stories converge, building to a final conflict. Schaffa exists as a father-figure to Nassun in this book, continuing his transformation and showing how even the Guardians have been victims through history.
I enjoyed this series, but I wonder if I missed some of the finer points while struggling to figure out how the world worked. One example is that I didn’t understand why Essun would partially turn to stone for using orogeny after she had activated the obelisk gate. I think it may be fun to re-read all of the books to catch those details on a second read, but I don’t often have time to do this. (Too many books, too little time!)
If you’re looking for fantasy with a unique setting, world-building, and realistic characters, then this is a great series. Themes throughout the books include looking at oppression of different races and classes, suppressing history, and a difficult mother-daughter relationship.
