Earth Logic — Laurie J. Marks

A SWEEPING DRAMA OF WAR, INTRIGUE, MAGIC, AND LOVE

The nation of Shaftal has a new ruler, a woman with enough power to heal the war-torn land and expel the invading Sainnites. Or it would have a ruler if the earth witch Karis G'deon would consent to rule. Instead, she lives in obscurity with the fractious family of elemental talents that have gathered around her. She is waiting for some sign, but no one, least of all Karis herself, knows what it is.

Then the Sainnite garrison at Watford is attacked by a troop of zealots claiming to speak for the Lost Gdeon and a mysterious and deadly plague attacks the land, killing both Sainnites and Shaftali. Karis must act or watch her beloved country fall into famine and chaos. And when Karis acts, the very stones of the earth sit up and take notice.
