The Stone Sky

The earthshaking conclusion to Jemisin's powerful postapocalyptic Broken Earth trilogy (after The Obelisk Gate) finds the fate of a damaged world in the hands of a mother, who wants to save it, and her daughter, who wants to destroy it. Essun believes she is the only person left alive who has the power and skill to open the magical Obelisk Gate and wield its power to save her cataclysm-rocked planet, the Stillness, which is being torn apart by an ancient experiment that got out of hand. But she is caught between that duty and her need to find Nassun, her 10-year-old daughter. Nassun's father killed her brother and took her away because both children shared their mother's dangerous talent; he hoped to "cure" her, but instead she has become incredibly powerful. Essun's search grows urgent when she learns that Nassun is being guided by a dangerous mentor with plans of his own. Jemisin draws Essun and Nassun perfectly, capturing a mother's guilt and pride and a daughter's determination to survive on her own terms. The Stillness, where ancient science is powered by magic, is unforgettable. Vivid characters, a tautly constructed plot, and outstanding worldbuilding meld into an impressive and timely story of abused, grieving survivors fighting to fix themselves and save the remnants of their shattered home.
