A rare hybrid of vampire and werewolf, Riley Jenson and her twin brother, Rhoan, work for Melbourne’s Directorate of Other Races, an organization created to police the supernatural races–and protect humans from their depredations. While Rhoan is an exalted guardian, a.k.a. assassin, Riley is merely an office worker–until her brother goes missing on one of his missions.

The timing couldn’t be worse. More werewolf than vampire, Riley is vulnerable to the moon heat, the weeklong period before the full moon, when her need to mate becomes all-consuming.… Luckily Riley has two willing partners to satisfy her every need. But she will have to control her urges if she’ s going to find her brother. Easier said than done as the city pulses with frenzied desire, and Riley is confronted with a very powerful–and delectably naked–vamp who raises her temperature like never before. In matters carnal, Riley has met her match.

But in matters criminal, she must follow her instincts not only to find her brother but to stop an unholy harvest. For someone is doing some shifty cloning in an attempt to produce the ultimate warrior–by tapping into the genome of nonhumans like Rhoan. Now Riley knows just how dangerous the world is for her kind–and just how much it needs her.

Riley Jenson, half-werewolf and half-vampire, joins forces with Kade, a sexy warrior, as they flee for their lives from a new and deadly conspiracy aimed at creating the ultimate warrior.

Dhampire Riley Jenson, a hybrid of vampire and werewolf, journeys to Melbourne and into the heart of the city's seductive and dangerous urban underworld to find an enigmatic killer who has been using a nightclub that caters to its denizens' every fantasy as his stalking grounds.

She's hunting a killer— and shattering every boundary— she's ever known. Part vamp, part werewolf, Riley Jenson plays by her own rules, whether it’s her stormy love life or her job as a guardian. But when her family’s alpha male demands that she solve the mystery of a vanished girl, Riley can feel a trap closing in around her.

Because the job comes with a catch: if Riley fails, her own mother will die. Now the stakes are raised, the hunt is on...and when more women vanish, Riley is caught between a lover who demands that she give up her work, a serial killer who knows no boundaries, and a club where humans and supernaturals mix—at their own peril.

Thrust into a realm of seduction and violence unlike any she could have imagined, Riley has to battle to save everything she holds dear. But the ultimate hunt has only just begun....

Half-vampire, half-werewolf guardian Riley Jenson must use all the dhampire powers at her command as she tracks two vicious serial killers--one who targets high-society strumpets and their rich, powerful lovers, and the other who selects victims with tragic pasts--aided by sexy vampire Quinn.

After her soul mate is killed, shape-shifting werewolf and vampire Riley Jenson takes on a new case that forces her to go up against an enemy from her past who is determined to strip Riley of everything that gives her life meaning, in the final installment of a nine-book series.
