Forced to wed the scarred and silent Duke they call the Monster of Greystone , she becomes the Duchess no one wanted. The bride chosen out of debt, not desire. Yet within Greystone’s cold halls, Cecily begins to glimpse the man behind the rumors: haunted by loss, bound by guilt, and desperate to keep his heart untouched. When whispers of his past resurface, threatening the fragile peace between them, she must decide whether love born of obligation can survive the ghosts that will not rest. A lush, slow-burn Regency romance for readers who crave emotional intimacy, lyrical prose, and the quiet ache of two wounded souls finding light in the dark.
