Lady Victoria Gardella Grantworth de Lacy has been a vampire slayer for a year, balancing her life as a peer of Society with the dangerous role that takes her out on moonlit streets, stake in hand. She has learned brutal and heartbreaking lessons about the sacrifices that must be made in order to save humanity from the evil that preys upon it. Now, in Italy, a powerful vampire is amassing the power to control the souls of the dead. As Victoria races across Europe to stop what could be the most deadly army the Gardellas have ever faced, her unlikely companion is Sebastian Vioget, a man as tempting as he is untrustworthy. But when Victoria discovers that she has been betrayed by one of her most trusted allies, the truth will challenge all her powers as a vampire hunter - and as a woman.
