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.
