By day, Detective Naira Ward is the sharpest mind in Blackthorn’s police force — calm, ruthless, and unbreakable. By night, she’s the hidden Alpha of the Hollowfang Pack, burdened by duty and a heart that’s never found its mate. When a string of savage murders shakes the city, all trails lead to the Rogue Moon Riders — a dangerous biker brotherhood where wolves, panthers, and Lycans rule the underworld. Naira is ordered to go undercover, to expose the killers hiding among them. But the moment she meets Jaxon, Cade, and Rhett, her wolf stirs. Her mark burns. Three men. Three mates. One impossible truth. Now, trapped between her badge and her bond, Naira must play both sides — detective and Alpha, predator and prey. The deeper she digs, the more she realizes the murders are part of a darker game, one that could destroy the fragile line between her two worlds. And when the real killer steps into the light, Naira will have to choose… Justice. Or the mates fate never meant her to have.
