Deathmark

Purple spur and silver thread, Waste away until you're dead. Necromancers infest the land of Alderyth, fueling a dark plague that always kills its victims. For Nell, it's more than a story told by travelers. The deathmark claimed her family and fated her to a life of servitude. When a battered old hag collapses in her arms, suspicion swirls through her paranoid town. Could Nell be a carrier of the plague? She flees rather than submit to prying authorities, but not without trouble.
The deathmark dogs her footsteps, and her best escape might lie with a reclusive man who knows far more than he should about the curse.
