Full Moon Rising

In the first book of the New York Times bestselling Riley Jenson Guardian series, a vampire-werewolf hybrid must overcome her animal instincts'and the allure of a devilishly handsome vampire'to save her brother. Meet Riley Jenson, a rare vampire-werewolf hybrid who's ready to howl, prowl, and sink her teeth into crime. She and her twin brother, Rhoan, work for Melbourne's Directorate of Other Races, an organization created to keep the supernatural in check. While Rhoan is an exalted guardian, Riley is merely an office worker, until her brother goes missing on one of his missions and it's up to her to find him. The timing couldn't be worse. More werewolf than vampire, Riley is vulnerable to the moon heat, the period when her need to mate becomes all-consuming.
