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. The Obsidian Covenant is a dark dystopian reverse harem romance featuring a morally gray FMC, four obsessive MLs, found family dynamics, enemies-to-lovers, rejected mate redemption, and a slow-burn that explodes into high heat. Perfect for fans of The Cruel Prince meets Den of Vipers in a post-apocalyptic wasteland. No choosing. No apologies. No mercy.

Now Mars is trapped in a fantasy world as a nobody, and the gorgeous, cruel Crown Prince who just kidnapped him thinks he's a spy. Keith Elarion's solution? Keep Mars under his personal, infuriatingly attractive supervision. Mars’s plan is simple- survive, avoid the plot, and find a way home. But the prince is nothing like the two-dimensional villain from the book. Keith is all intense green eyes and confusing, rough kindness, and he’s decided Mars is his to keep. When Mars accidentally unleashes a power he should not possess, he becomes the key to a conspiracy that runs deeper than the novel ever revealed. His meddling changes everything, accelerating a plot that was supposed to take years. To top it off, a cryptic bird-god just told Mars he's not just a lost college student.
