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.

In a divided world where witches, demons, elves, and humans live under fragile peace, a young witch named Seraphina Vale discovers a forbidden power within her blood a power that once destroyed kingdoms. When Seraphina saves a wounded stranger during a night raid, she unknowingly crosses paths with Prince Kael, heir to the Demon Throne. Their encounter awakens an ancient curse known as the Bloodbound Mark, binding their fates together. As word spreads of the mark’s return, witch councils, demon lords, and human hunters all begin hunting her believing her death will prevent another war. Haunted by visions of a powerful witch from centuries past, Seraphina flees with her friend Lira, only to learn her magic is mutating beyond control. Forced into an uneasy alliance with Kael, she discovers that the mark connects them not as enemies, but as halves of one prophecy a curse meant to either unite or destroy all realms. As the world prepares for war, Seraphina is betrayed by her own kind and hunted by Demon Hunters led by the relentless Captain Ryn. Meanwhile, Kael hides a devastating secret: his father, King Azarel, plans to use Seraphina’s blood to merge the demon and human worlds forever. Torn between loyalty and love, Kael risks everything to protect her even as the curse begins consuming them both.

"Custom demanded that Prince Urban get a love mark tattooed to the side of his left eye as an infant, just like the rest of his people, but to him, the stupid things have only brought on the scorn of his father, the misery of his siblings, and caused his entire kingdom to go broke from fighting so many wars over the irritating ink stains. When Urban’s sister must travel to Donnelly, the kingdom within the sand, for her arranged marriage to align two realms, he goes with her. But he no sooner steps foot inside their castle than his mark starts itching like a son of a bitch, telling him his one true love is near. It just figures, though, that the woman meant for him is completely forbidden. Now he must decide if he should ignore the persistent mark, telling him she's the one, in order to avoid a possible war between kingdoms, or if he should discover whether she's worth risking everything for so they can be together. Either way, his life gets sucked into chaos with threats of beheadings, dark magic lurking, castle traitors scheming, and sword fights eminent. Who knew one little tattoo could cause so much trouble? (ONE TRUE LOVE is the author’s first attempt at a fantasy romance. Please forgive her; she might’ve read an overabundance of Cassandra Gannon, Sarah J. Maas, and Eve Langlais books, then gone off to watch too many episodes of Supernatural, Game of Thrones, and Outlander, because this was the outcome.)"

Seraphine Vale is whisked away to Aetherborn Academy after a terrifying magical incident, she expects answers, not four dangerously captivating boys who seem unnervingly drawn to her. Alaric, the cold vampire noble. Kade, the brooding werewolf with eyes like storms. Damien, the charming dragon prince. And Lucien, the beautiful, unreadable incubus who invades her dreams. Each boy reacts to Seraphine as if they’ve known her far longer than she’s been alive… and each one’s powers surge unpredictably around her. As forbidden feelings spark and jealousy rises, Seraphine discovers a chilling truth: a prophecy ties her fate to theirs and to a sealed ancient power capable of either saving or destroying their world. Dark forces begin stirring beneath the Academy, hunting her magic… and her heart. To survive, Seraphine must unravel the mystery of who she really is and which boy she can trust when love itself might set the prophecy in motion. Because awakening the Aetherborn doesn’t just change her destiny. It changes everyone around her.
