In a world ruled by duty, faith, and inheritance, love can be the most dangerous rebellion of all. Paris, 1730. Thirteen-year-old Henrietta Waldegrave arrives to live with her Catholic grandparents, her life shaped by secrets: a father who has renounced both his faith and his daughter, and a mother long dead. Raised among aging aristocrats, Henrietta is promised to a man twice her age in a match made for money, not affection. What follows is a life compromised by her husband's lies, an unwanted pregnancy, and a scandalous affair. Torn between duty and desire, Henrietta defies the expectations of her class—abandoning her child in pursuit of a life on her own terms. But the price is steep: disgrace, estrangement, and lifelong regret. Years later, her daughter Barbara is drawn into a dangerous game of her own. When she's offered a marriage that will restore her birthright—but cost her youth—Barbara must decide how much of herself she's willing to sacrifice for power, freedom, and a legacy written in other people's hands… Spanning generations, courts, and countries, The Jacobite's Heir is a haunting tale of family, betrayal and resilience, and the impossible choices faced by women in a world that was never made for them.
