The Obelisk Gate - The Broken Earth 2. - N.K. Jemisin

This is the way the world ends, for the last time. 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.
