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.

One moment he had just read the strangest book he had ever come across, the next he was stumbling into the world of that same book. 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. He's the son of the goddess who made this world. To save Keith, stop a divine war, and maybe finally kiss the man he falls hopelessly in love with, Mars has to do the one thing the book never planned for: he has to rewrite fate itself.

Sadie Ozoa wants to chase her dreams and doesn’t want to take no for an answer, but it feels like she doesn’t have a choice.

As they go on the journey to create their own world, Anya sees that Sadie is more than an outcast and Sadie sees that Anya is more than just a star--they are each other’s world. But with the world that is against their odds, will they be able to show their truth?
