Shattered Pillars — Elizabeth Bear

The Shattered Pillars is the second book of Bear's The Eternal Sky trilogy and the sequel to Range of Ghosts. Set in a world drawn from our own great Asian Steppes, this saga of magic, politics and war sets Re-Temur, the exiled heir to the great Khagan and his friend Sarmarkar, a Wizard of Tsarepheth, against dark forces determined to conquer all the great Empires along the Celedon Road.

Elizabeth Bear is an astonishing writer, whose prose draws you into strange and wonderful worlds, and makes you care deeply about the people and the stories she tells. The world of The Eternal Sky is broadly and deeply created -- her award-nominated novella, "Bone and Jewel Creatures" is also set there.
