Broken Earth (trilogy) (2015)

Wowowow, this might be my favorite fantasy series ever!

A SEASON OF ENDINGS HAS BEGUN.

IT STARTS WITH THE GREAT RED RIFT across the heart of the world's sole continent, spewing ash that blots out the sun.

IT STARTS WITH DEATH, with a murdered son and a missing daughter.

IT STARTS WITH BETRAYAL and long-dormant wounds rising up to fester.

This is the Stillness, a land familiar with catastrophe, where the power of the earth is wielded as a weapon. And where there is no mercy.
