The Duke Steals Hearts & Other Body Parts

Wielding a magic that allows him to pop off limbs, con-artist Phyllis ransoms body parts to make a living. At least until his cold heart is moved when a mark claims his sister, Adeline, was taken.
Adeline is not the only missing girl in their seedy city, and
Phyllis' best chance to unravel the mystery is to become Lord Phillip of Rabbiton and strike a deal with the ambitious madame, Adeline's former employer, for info on his leads. As a duke, Phillip finds the girls who are not dead—but undead. And when the madame finds out, she twists Phillip into helping her with her plans to rule the city.
To cement his future as a duke, save his new family of mostly-dead girls, and earn Adeline's affection, Phillip will have to stop the madame and discover the depths of his magic—before his own lies destroy him.
