Keeper of the Night (Keepers: L.A. Series #1)

New Keeper Rhiannon Gryffald has her peacekeeping duties cut out for her—because in Hollywood, it's hard to tell the actors from the werewolves, bloodsuckers and shape-shifters. Then Rhiannon hears about a string of murders that bear all the hallmarks of a vampire serial killer, and she must confront her greatest challenge yet. Together with Elven detective Brodie McKay, they head to Laurel Canyon, epicenter of the danger, where they uncover a plot that may forever alter the face of human-paranormal relations.
