Flame Isfree and the Feather of Fate

Bucking thousands of years of tradition, Flame ran away from her elven heritage, her glorious destiny, and her arranged marriage. Now she's an expert treasure-finder in the human world, one job away from buying out her indenture and setting up a tower somewhere full of pretty things and pretty men. Just one more job--but her employer doesn't know exactly what they're questing for, and also the world has changed since his map was drawn.
Flame can handle all that with her usual sarcasm and skill, but when her intended husband turns up at the fateful meeting of the moons, ready to fulfill his destiny and help her save the world, she really just wants to run again. All Flame really wants to do is nothing, but failure in the quest means a price on her head. Failure in the world-saving would be even worse. Why can't everyone, fate included, just leave her alone?
