“This isn’t right…” I whispered. But my stepbrothers grabbed me anyway, their warm hands roaming my body. “You belong to us,” Sylver said darkly. “You’re our pet. Our sub. And that won’t ever change.” ————- My mother and I have been running for three years—from Eryndor Blackshade, the vampire cult leader obsessed with owning me. Just when he finds us again, my mother makes a desperate move: she marries King Reid Thornevale, the most powerful Lycan in the Blood Hollow Pack. But Reid comes with a dangerous secret—triplet hybrid sons, born of vampire and werewolf blood. They’re ruthless, cursed… and now, my stepbrothers. From the moment Sylver, Cassian, and Rylan Thornevale lay eyes on me, something ancient stirs—twisted, forbidden, and hungry. A fire that scorches morality and melts all reason. Our connection isn’t just wrong. It’s deadly. Because the Thornevale bloodline is cursed—descendants of Elder Varek, the first vampire–werewolf hybrid, sealed away centuries ago. The curse awakens under every Red Moon, turning them into monsters driven by bloodlust and desire. Now I’m caught in the middle. Between a cult that wants to sacrifice me… And stepbrothers who want to claim me. And I don’t know which fate will destroy me first.

Kerry's life spirals into chaos when her mother marries a vampire. As someone who thought vampires were just myths, she struggles to accept their reality. But nothing could prepare her for her dangerously seductive new stepbrother, who seems determined to make her his. Is their bond a twist of fate, or something far darker?
