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?

In a world where the moon shattered and the strong devoured the weak, Neoma Solstice is nothing. A scentless Null. A ghost. A mistake. Until the day she saves a dying Lycan warrior with a touch, and her secret is revealed: she's Void-Born, the rarest mutation in existence. The same power that makes her invisible makes her invaluable—a living weapon that can cure the incurable Feral Rot plaguing the Lycan Ascendancy. Captured and collared, Neoma is forced to serve as "Tether" to Unit Vanguard: four elite soldiers on the brink of madness. Barzil, the ruthless Commander who sees her as a mission. Wolfy, the cold Tactician who sees her as a puzzle. Viggo, the feral Berserker who sees her as salvation. Guller, the fallen Priest who sees her as redemption. They own her contract. They control her life. They swear she's just a tool. But tools don't make their masters kneel. As Neoma's power grows, so does the threat she poses to the regime that enslaved her. When the prophesied Blood Moon rises, she'll have to choose: remain the Ascendancy's battery, or become the Void that devours them whole. Some bonds are forged in blood. Some in magic. Theirs was forged in desperation—and it might be the only thing strong enough to save a dying world.
