A rare hybrid of vampire and werewolf, Riley Jenson and her twin brother, Rhoan, work for Melbourne's Directorate of Other Races, an organisation created to police the supernatural races - and protect humans from their depredations. While Rhoan is an exalted guardian, aka 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. For someone is doing some illegal 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.
Australian author Arthur's fast-paced fantasy-romance, the first in a new series, introduces part vampire, part werewolf Riley Jenson, who works for Melbourne's Directorate of Other Races, as does her twin brother, Rhoan. When Rhoan goes missing, a naked yet powerful vampire, Quinn, appears on Riley's doorstep and asks for her aid. Riley and Quinn team up to find Rhoan, investigate the mysterious deaths of Directorate agents and determine who's been creating vampire and werewolf clones. Despite their mutual attraction, Quinn once heartbroken by a werewolf lover will never fully trust another werewolf, but that doesn't stop him from helping Riley through the lust that engulfs werewolves in the days leading up to the full moon. Strong, smart and capable, Riley will remind many of Anita Blake, Laurell K. Hamilton's kick-ass vampire hunter. While Arthur (Beneath a Rising Moon) occasionally loses control of her plot as she sets the stage for later books, and some romance readers may be put off by the lack of monogamy, fans of Anita Blake and Charlaine Harris's Sookie Stackhouse vampire series will be rewarded.
