Both — Marsheila Rockwell

Bound by an oath made before she was born, Kij, a daughter of the forest, must travel into the heart of the desert to determine the fate of a man she's never met. On a journey where old enemies and new traditions prove equally dangerous, she quickly learns that justice is sometimes as hard to come by for the judge as it is for the accused and that, in the Sea of Sand, there is no such thing as mercy.
