Sanctuary

Pushing papers at a werewolf sanctuary is the least appealing assignment Aviva could have wished for. It's the bottom rung of the career ladder for a vampire, a job that will leave her isolated from most of her kind as she watches over members of a species whose very existence threatens the secrecy of the supernatural world. Her only consolation is the promise of peace, quiet, and a chance to impress the elders over the course of an easy assignment. After all, the werewolves may be troublesome, but they've kept their own secrets for a century.
But the situation at the sanctuary is not what she expected, and Aviva's hopes of easy success are quickly dashed. Age-old tensions between vampires and werewolves come to a head when a human in a nearby village is found brutally murdered and suspicion lands squarely on the sanctuary's supernatural inhabitants.
When the pack leaders refuse to turn the killer in to face justice, Aviva knows her elders will do anything to keep their world safe from humans, even if it means wiping out the werewolves for good. With the help of a mistrustful female and a relentlessly tempting alpha male, it will be up to Aviva to overcome the instinctive hatred between their species and catch a murderer before the human world takes notice—and before the sanctuary turns into a battleground.
