With the conclusion of the nightmarish Marvolio Killings a hollow success for the coterie, Joseph Rose-Price and Kamila Mansouri are the new up-and-comers in the vampire world – but they don't have long to celebrate. The duo's young apprentice Vittoria Giovanni has vanished leaving only bloodied bedsheets and a shattered pearl necklace in her wake as the forces of chaos gather on the horizon in the form of the Sabbat, a violent sect of tradition-breaking kindred. Riding their fame and influence they must unite the disparate leaders of Los Angeles's many vampiric territories, convincing them before it's too late that the Sabbat pose a true danger to the stability of the city. And when Charlotte Devereux, Hollywood's eccentric Keeper of Elysium, switches sides and joins the party, will our heroes finally have enough power and authority to prevent L.A. from being subjugated by the QUEEN OF THE NIGHT?
