Dellaria Wells, petty con artist, occasional thief, and partly educated fire witch, is behind on her rent in the city of Leiscourt—again. Then she sees a "wanted" sign seeking Female Persons, of Martial or Magical ability, to guard a Lady of some Importance prior to the celebration of her Marriage. Delly fast-talks her way into the job and joins a team of highly peculiar women tasked with protecting their wealthy charge from unknown assassins. Delly quickly sets her sights on one of her companions, the confident and well-bred Winn Cynallum. The job looks like nothing but romance and easy money until things take a deadly (and undead) turn. With the help of a bird-loving necromancer, a shapeshifting schoolgirl, and an ill-tempered reanimated mouse named Buttons, Delly and Winn are determined to get the best of an adversary who wields a twisted magic and has friends in the highest of places.
