The Obelisk Gate by N.K. Jemasin
The season of endings grows darker, as civilization fades into the long cold night.
For Essun her journey has yield
ed secrets and a reunion she never expected. She has found shelter in Castrima, but not her missing daughter. Instead there is Alabaster Tenring, destroyer of the world, with a request only Essun can grant.
Meanwhile the Nassun's expedition with her father takes her north in search of the fabled moon and a promised cure for her orogeny. It's a road that promised to lead her to new discoveries and a stranger from Essun's past with his own dangerous secrets.
As the season draws in, both Essun and Nassun will face loss, betrayal and choices that will change not only their own lives, but the future of their world.
Breathtakingly ambitious, blisteringly brilliant and peopled with a cast of unforgettable characters, The Broken Earth trilogy - beginning with The Fifth Season, continuing in The Obelisk Gate and concluding with The Stone Sky – is the first series to win the Hugo best novel award three years in a row. A ground-breaking masterwork of contemporary fantasy fiction, this is a series not to be missed.
