The Obelisk Gate (The Broken Earth, Book #2) by N. K. Jemisin
Essun's missing daughter grows more powerful every day, and her choices may destroy the world in this "magnificent" Hugo Award winner and NYT Notable Book. (NPR)
The season of endings grows darker, as civilization fades into the long cold night.
Essun -- once Damaya, once Syenite, now avenger -- has found shelter, but not her daughter. Instead there is Alabaster Tenring, destroyer of the world, with a request. But if Essun does what he asks, it would seal the fate of the Stillness forever.
Far away, her daughter Nassun is growing in power -- and her choices will break the world.
N. K. Jemisin's award winning trilogy continues in the sequel to The Fifth Season.
