Ember and Ash — Pamela Freeman

Two peoples have been fighting over the same land for a thousand years. invaders crushed the original inhabitants, and ancient powers have reluctantly given way to newer magics. But Ember was to change all this with a wedding to bind these warring people together -- until her future goes up in flames.

Ember's husband-to-be is murdered by a vengeful elemental god, who sees peace as a breach of faith. Set on retribution, she enlists the help of Ash, son of a seer. Together they will pit. themselves against elementals of fire and ice in a last attempt to end the conflicts that have scarred their past.

Ember and Ash is set in the same world as Pamela Freeman's acclaimed Castings Trilogy.
