Beneath Ravenholt's dying moon, bloodlines were never meant to cross. Lyra Mournshade - half vampire, half something else - has spent her life in the shadows, hunted by her own kind and haunted by the voice of a mother long dead. When the Order of Ash begins slaughtering hybrids across the realm, Lyra's secret threatens to burn the fragile peace between vampires and wolves. Kael Thornbane, Alpha of the last free pack, swore never to trust anything touched by fangs. Yet when fate pulls him into Lyra's storm, he feels her before he ever sees her - a heartbeat that calls to his own. As hunters close in and the veil between worlds begins to tear, Lyra and Kael find themselves bound by a power older than blood. Their union could shatter the curse that divides their races... or destroy everything they love. In a world where desire is dangerous and loyalty cuts deep, their greatest sin will be the promise they can't unmake. Blood and Moonbound: The Hybrid's Vow is a dark supernatural romance of love, legacy, and the dangerous beauty of becoming whole.
