Annelida Asher is a witch, cat mom, exasperated granddaughter, and essentially a glorified bounty hunter for the Department of Inhuman Affairs. She spends most of her time riding around Chicago on her ill-tempered donkey, chasing petty criminals, and eating baked goods. When a routine job goes awry, however, she finds herself in the middle of a three-hundred-year long string of brutal, ritual murders. Expected to solve what appears to be an unsolvable case with only her new partner and a strange, demonic wolf-dog for help, Asher is rapidly running out of patience¿and time.
