Every thousand years, the barrier between the human realm and the Shadow Court weakens. A mortal woman, Alina, is chosen as the 'Veilbound'—a living sacrifice meant to keep the realms apart. But when the Shadow Prince, Kael, comes to claim her, he doesn’t kill her. Instead, he marks her as his consort to secure his throne. Bound by an unbreakable vow, Alina is forced into a world of treacherous courts, forbidden magic, and seductive power struggles. The deeper she falls into Kael’s world, the more she questions whether she’s the prisoner…or the key to unleashing something far darker.
