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.

"My dragon chose her before I even looked at her. But that doesn't mean I’m keeping her." As the Dark Prince of the empire, everyone fears me. At the sound of my name, the crowds fall silent; at my glance, heroes fall to their knees. My soul is just as black as the dragon with whom I share my thoughts. I don't need anyone. Especially not a foul-mouthed thief dragged off the streets. The girl, Eira... she is chaos incarnate. With her snow-white hair and lethal green eyes, she looks like an angel, but she fights like a demon. At the Selection, she did not bow to me. Instead, she looked me in the eye, and I saw the same fire in her that consumes me. I chose her. Not to save her from misery, but to break her. To forge her into a warrior for the coming war. But there is something I didn't count on. My dragon has become obsessed with her. And as our angry arguments grow hotter and the boundaries of physical training begin to blur, I must realize a terrible truth: The girl is not afraid of the darkness. She is the flame itself, capable of incinerating my world. Two scarred souls. A single chance for survival. Will we kill each other before the enemy reaches the gates?

In the quiet of the forest, the darkest fears are born. The people of Dunballan, harbour a dark secret. A secret more terrible than the Beast that stalks the dense forests of Dunballan. A secret that holds David McCavendish, last in a long line of Lairds, in its unbreakable grip. It’s down to Sally, David’s lover, to free David from the sinister clutches of the Beast. But, with the whole town against her, she must ally herself with an ancient woodland force and trace Dunballan’s secret back to its bitter origins. Those origins lie within the McCavendish family history, and a blasphemous heresy that stretches back to the beginning of time. Some truths are too terrible to face, and the darkest of these lie waiting for Sally, in the Quiet Places. ©️ Crystal Lake Publishing
