The Darkest Kiss - Number 6 in series

Dark secrets. Dangerous seduction. It all begins with a kiss... With a werewolf's uncanny instinct for danger - and vampire blood coursing her through her veins - Riley Jenson is an officer for the Directorate of Other Races, an organisation created to police supernatural beings. Now she's hunting for a killer who is targeting the rich and the powerful of Melbourne's society... But for Riley the case takes a chilling turn when a second killer - a crazed young vamp - starts leaving a trail of mutilated bodies of his own.
Riley knows she's got the skill and cunning to catch two serial killers at once, until one of them strikes inside her own tight-knit clan - and a sexy beast of a vampire re-enters her life to aid in the hunt. His name is Quinn. He's lived forever, shed blood and shared pleasure - and he's the only man over whom Riley has absolutely no control...
