All powerful rejected daughter forced to marry aloft cold duke

Abandoned in a rural village to rot, Lyra, the beautiful, rejected daughter of a powerful family, has transformed her solitude into strength. She cultivated unparalleled martial arts, mastered ancient medical techniques, and built a shrewd business empire, secretly protected by an elite all-female assassin guild she forged herself. Her influence subtly extends through hidden connections with powerful nobles and even the Royal Family. Now, the family who cast her aside demands her return. Her half-sister, betrothed to the aloof, formidable Duke Kaelen, has vanished, and Lyra is commanded to take her place. Forced back into a world that despises her, Lyra must navigate treacherous court politics, protect her hidden life, and confront the icy duke, all while battling the ghosts of her past and the schemes of those who wish her ill.
