A rare hybrid of vampires and werewolves, Riley Jenson and her twin brother Roan work for the Melbourne Office of Other Races, an organization created to protect supernatural species and to protect humanity from their atrocities. While Roan is a high-ranking guard—in other words, an assassin—Riley is just an office worker... until her brother goes missing during one of his missions. I couldn't imagine a worse moment. More of a werewolf than a vampire, Riley is extremely sensitive to the waxing moon in the week before the full moon. It is during this period that her need for mating becomes all-consuming. Fortunately, Riley has two partners who willingly satisfy her every desire. But she will have to control her attraction if she is going to find her brother. Easier said than done when the city is full of boiling passions, and Riley herself is faced with a very powerful and stunning, naked vampire who inflames her passion like no one before. For carnal pleasures, Riley has found a mate. But to expose the atrocities, she will have to trust her instincts, and not only in order to find her brother, but also to stop the terrible harvest.
