Reaper's Order - Founders Series, #1

Fear of the blight consumes the people of Verrin. It's up to reapers like Victoria to drain blight-infected humans before they turn into monstrous creatures who feast on human flesh. Freelance reaping doesn't pay the bills and Vic's dream of joining a Reaper's Order is finally within her grasp. Until she uncovers a terrible truth-a truth that will kill her sister. Vic witnesses members of an Order kill the citizens who they are sworn to protect.
As danger closes in from all sides, Vic hunts for safety for her and her sister. But where do you hide within the confines of a walled city? Vic faces an impossible choice: expose the corruption and doom them both to banishment beyond the walls of the only home they've ever known or fall in line to protect her family.
