Searching for clues to her murder, D’Eon discovers his sister’s life in the King’s court was more than jeweled gowns and priceless perfumes. It involved dark sorcerers, manipulative royals, and a violet-eyed vixen whose dangerous power turns innocent mongrels into slobbering, rabid monsters. D’Eon and his comrades slip from Versailles to Russia, seeking an emperor who appears to control magic-wielding followers. And serving a queen who seems far too pleased to have Lia’s spirit possess her brother’s body. A tormented beauty’s soul that is not resting in peace, but is alive and well—and looking for vengeance.
