Venoma Noir, the fourth Sister of Power, proves to be the most challenging yet for Viktor Brandewyne. She sets him to retrieve an amulet stolen by a notorious slave trader with a reputation for ruthlessness to rival Viktor's and a talent for black magic. She also possesses the power to turn the siren, Belladonna, against him; and the Sister will use every tool and opportunity she can to kill the pirate-turned-vampire before he can complete his quest.
