I live double lives, but with one very strict rule: never get involved with the clients. By day, I plan weddings I'll never have. Every bride who calls on me gets the wedding of her dreams. And even though no man's ever wanted to end up with me, watching the joy on my brides' faces is enough. By night, I put on a mask and become the comfort I can't find anywhere else. Just an hour of quiet, honest company for strangers who've run out of people to trust. It's not romance - not even close. But I get my own kind of comfort from it too. Then three men walk into my carefully guarded life, all at once, all determined to break my one rule: one I used to hate, one I'm not allowed to see, and one who's already trouble next door. I have a very terrible feeling I only need to be afraid of one of them - the Stranger in My Bed.

Detective Casie Blackwood thought she'd left her supernatural past behind when she joined the police force ten years ago, fleeing the shame of public mate rejection and family abandonment. Now, ritualistic murders are forcing her back into a world she desperately wanted to forget. Three human victims have been discovered with surgical precision wounds and ancient symbols carved into their palms—markings that point to forbidden blood magic from before the supernatural communities established peaceful coexistence. When Casie finds a note written in the old pack language reading "The Hunt Begins," she realizes someone is deliberately targeting humans to harvest their primal fear, threatening to expose the entire supernatural world. Partnered with Detective Rick O'Connor, who remains unaware of her true nature, Casie must navigate the investigation while concealing her enhanced senses and knowledge of the supernatural. The wounds aren't from blades—they're fang marks. The positioning isn't random—it's ritualistic. And the killer's scent carries a terror that suggests they're being hunted by something even more dangerous. Forced to break ten years of silence, Casie contacts her estranged brother Elias, learning the symbols are ancient binding marks used to channel supernatural energy across factional boundaries. The killer needs seven sacrifices total to complete a ritual that will shatter the barriers between the human and supernatural worlds. With three victims already claimed and only four days until the next lunar cycle, time is running out. As federal agents circle and media attention intensifies, Casie must choose between maintaining her carefully constructed human life and embracing the supernatural heritage she rejected. The investigation isn't just about stopping a killer—it's about preventing an all-out war that could destroy both worlds she's sworn to protect.
