This is the story of two celestial bodies, the Earth and the Moon, their orbits closing towards catastrophe and devastation. This is the story of two women, a mother and a daughter, their paths destined to cross in tumult and tragedy. This is The Stone Sky, the third volume of The Broken Earth series from author N. K. Jemisin.

Essun awakens, possessed of the power of Alabaster Tenring, and learns that the Moon is approaching, bringing with it a tenuous opportunity to end the Fifth Seasons forever. But her daughter Nassun, possessed of a fratricide’s guilt, has her own plans for the great stone in the sky. The decisions and actions of these women have already wrought and wracked the world, but now one of them may change it permanently. And the other may end it.

Perilous journeys, heartbreaking endings, and extraordinary revelations about everything from the nature of magic to the nature of humanity speed this tale.
