"I slam into him and he screams. A hoarse, broken, beautiful noise bursts out of him as I drive in all at once, a harsh, staking claim. He’s gripping me so tight I can barely breathe. He’s fire. He’s home. He writhes, his hands clawing at the sheets. I force myself to be still, to wait and let him stretch, to let his body take me. I’m buried so deep I feel like I’m touching his soul." Kieran Arnulf is an Alpha with a target on his back. Inheriting a pack broken by his father’s cruelty, he's determined to rule with mercy rather than fear. But to the vipers on his council, mercy looks a lot like weakness. When a massive, tattooed warrior from the enemy Redmaw pack surrenders at his gates, Kieran makes a controversial choice. He allows the wolf to come inside. Alexei Basov is dangerous, insolent, and far too attractive for Kieran’s peace of mind. He claims to be a defector with vital intel on an impending war, but he looks at Kieran like a meal he’s dying to devour. He’s a brawler who solves problems with violence, a stark contrast to Kieran’s polished diplomacy. As assassins strike from the shadows and political tension reaches a breaking point, Kieran is forced to rely on the one man he shouldn’t trust. Alexei appoints himself Kieran’s shadow, protector, and personal tormentor. But the tension simmering between them is more than just political. Behind closed doors, the power dynamics shift. Kieran discovers that the only place he can truly let go of control is in the arms of the savage wolf who wants to claim him.

"He drags me from wall to table to wall again, like he can’t decide which surface deserves this. Wood bites my spine, the table squeals. His hands are everywhere, rough, greedy, feral. He palms my throat, my jaw, my hips. He fists a hand in my hair and angles my mouth. The kiss is vicious. He grinds me open with it. 'Kneel,' he says. The command is a shove under the skin. My legs fold. It’s humiliating how fast I go and how much I love myself for it." He owns my mouth. My body. My fucking soul. But I never said he could have my heart. Eli’s been chained before and it damn near killed him. So when he’s caught running through Blackthorn pack lands by Ronan Vale, the savage Alpha of Blackthorn, he's horrified when the brute marks and claims him. But Ronan doesn’t just bite. He binds. With ropes, with rules, with a voice that makes Eli's knees go weak and a touch that turns resistance into hunger. The bond between them is feral. And Eli hates how much he wants it, how much he wants Ronan, even when he has him spread out and shaking, marked and owned, begging to be filled so he’ll stop feeling empty. Eli swore no one would ever own him again. Then came the Alpha whose bond feels like a brand and a promise all at once. He hates how much he wants it. Ronan’s voice. Ronan’s hands. Ronan’s brutal, worshipful need. This isn’t love, it’s obsession. And Eli is afraid that he's starting to like it.

...“You can’t win this trial. The pack is against you. Your father is against you. Even your friend…” He paused. “Even she has betrayed you.” Kael’s eyes locked on mine, hard as iron. “So I’ll give you a choice. Trust me, and I’ll make sure you live.” “Trust you? You just claimed me like I was some prize to steal. You said you would kill me if I lost control.” “And I meant it,” he said, voice flat. “But I won’t let them tear you apart like animals. If you let me, I’ll fake your defeat. I’ll claim you fully... On the night of her eighteenth birthday, Lyra Vale’s first shift should have bound her to her pack. Instead, it marked her as the monster they fear most. Born under the cursed Blood Moon Oath, she is fated to either unite the supernatural world… or reduce it to ash. Now every faction wants her blood; the Vampire Courts whisper her name as the key to breaking their chains, while the Witch Sanctum swears she is a mistake of prophecy and her own pack and her family would rather see her buried than crowned. But fate is never merciful. Lyra’s soul is bound to a mate who is both her fiercest protector and her deadliest enemy. A boy who swore an oath that might kill her… and break her in ways no blade could. As betrayal coils tighter than love in a world where alliances shift like shadows and every truth has fangs, Lyra must decide: Will she chain the beast inside her or unleash it? This is because under the Blood Moon, even salvation tastes like blood, every choice bleeds and under the Blood Moon, will love be a weapon?

At Blood Oath Academy, no one arrives by chance—except Virelle Noctra. Marked by a power that shouldn’t exist, Virelle is summoned into a hidden world where vampires and werewolves train under fragile, ancient laws. But from the moment she steps inside, something is wrong. Her blood doesn’t belong to either side… yet both crave it. A ruthless vampire heir watches her like prey. A dangerous wolf alpha feels his instincts bend toward her. And beneath the academy, something older than both species begins to stir—something that recognises her. As alliances fracture and desire turns lethal, Virelle is pulled into a power struggle she doesn’t understand but can’t escape. The more her abilities awaken, the clearer the truth becomes: She isn’t just part of the war. She’s the reason it’s starting. And when the blood oath breaks, everyone will have to choose Kneel… or burn.

Aurora is torn between her duty and her desire for true love. As she navigates the complexities of court politics and magic she finds herself drawn to each of the four suitors, each with their unique personalities and abilities.
