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.

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.

Amelia Rose Vale has always been ordinary. Careful. Quiet. Human. Then an impossible letter arrives at her door, accepting her into Waycross Academy—a school she never applied to and cannot find on any map. By dusk the next day, Amelia steps through its gates and into a world where corridors shift without warning, rules are enforced but never explained, and every student around her is something other than human. At Waycross, Amelia is not just unusual. She is impossible. Her presence draws the attention of seven powerful men: a cryptic cat shifter who appears where he should not be, a dragon shifter who looks at her like he has waited years to find her, a restless fae bound by secrets and time, a demon whose calm hides dangerous hunger, a chaotic vampire who knows too much, an ancient guardian who teaches her how to survive, and a controlled mage mentor determined to keep his distance. Each of them recognizes something in Amelia that she cannot see in herself. As her strange power begins to wake, Amelia discovers her family name buried in forbidden records, and her supposed humanity becomes harder to believe. But being noticed at Waycross is dangerous. A jealous incubus queen wants her broken, hidden enemies are watching from beyond the Academy walls, and the school itself seems to be pushing her toward a truth no one will fully explain. Amelia thought she was falling into a nightmare. But Waycross did not choose her by mistake. And the monsters circling her may not be her downfall. They may be the first ones to kneel.
