Moonblood Vow

Moonblood Vow by Jess Rae is a dark fantasy romance where survival has a price-and desire can become a weapon. Nyra flees a cruel, sacred court after her father binds her to an ancient vow meant to turn her into something less than human: a living doorway for the hunger buried beneath the mountains. But the escape doesn't set her free-it awakens the tether at her throat, a moon-mark that pulls her toward forbidden magic.
and toward Draven, a stitched-shut prisoner with a monster locked behind his collar. Hunted across winter ridgelines by the King's men and haunted by a broker of old powers, Nyra and Draven are forced into the ruins of the Moon-Shrine, where vows become law and blood is currency. Every step forward tightens the bond between them, blurring the line between protection and possession, fear and longing.
To live, Nyra must learn to speak in the language of old stone-rewriting the meaning of "open" before the Mouth beneath the world claims her voice for good. A chilling, atmospheric dark fantasy romance full of dangerous magic, sacred horror, slow-burn tension, and a love that could either break the curse. or complete it.
