C. M. Waggoner The Ruthless Lady's Guide to Wizardry

A Tor.com Reviewers' Choice Best Book of the Year Sparks fly in this enchanting fantasy novel from the author of Unnatural Magic when a down-and-out fire witch and a young gentlewoman join forces against a deadly conspiracy. 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 the "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.
