Reaper

As a Death Warden, Ava Longbane is well acquainted with corpses. She collects the dead, checking for the sinister and untoward before adding them to the body cart. But she deals with the human dead, not the Whym. Never them. As creatures of innate magic, they're best avoided. Especially by someone like her, exiled, condemned -- as good as dead herself. But when one of them, a highborn elf turns up gutted, butchered by human hands, the elegant and unnerving local Whym inquisitor demands her assistance. She's dragged into a world of blood and magic, a world she'd do anything to escape, because 'as good as dead' just isn't close enough for some.
