The Duke's Dark Obsession

[Obsessive ML, Dark Historical Romance] On the night meant to seal her fate in silk and candlelight, Caelith Emberlyn discovers her new husband entwined in betrayal with her own cousin. Before the humiliation can swallow her whole, another man steps out of the shadows—dangerous, powerful, and far more terrifying than heartbreak. He is the feared Commander of the Shadow Imperial Guard, a man whose name alone stills the court and stains the capital with silenced dread. Where others see a cold enforcer of the throne, he sees only her—wronged, furious, and far stronger than she appears. And he offers her a choice. Stay. What her husband failed to give—loyalty, devotion, power—he vows to place in her hands in his stead. But this is no gentle rescue. Their alliance begins in secrets and smolders in the dark, a forbidden affair that could shatter reputations and topple dynasties. He is ruthless in war and relentless in love, determined to claim not only her presence at his side but the guarded heart she refuses to yield. Meanwhile, her repentant husband returns with soft words and tender promises, swearing to cherish her forever. Yet regret comes too late in a world where power is currency and affection is a battlefield. Caught between a contrite prince of light and a possessive shadow king who would burn the world to keep her, she must decide: Will she return to the safety of a love that broke her… Or step into the fire of a devotion fierce enough to consume them both?
