At a local vampire club, someone is beheading the clientele and the peace the Guardians are meant to maintain is getting shaky. Human and vampire fatalities escalate and Riley Jenson - a rare hybrid of werewolf and vampire - finds herself struggling to make sense of the murders and, in particular, her main suspect: the club's owner Dante Starke and his powerful sexual aura. And if things weren't bad enough, she's also torn between her love for Quinn and her connection with the unpredictable werewolf Kye - her soulmate. With the city on the verge of all-out war, Riley must not only capture the killer, but choose between the man she loves and the man she's destined to be with.
