Fortune's Darling: The Lost Heiress Returns

Candice Gale once saved the life of Simon Smith, the richest man in the capital, and through a series of mix-ups she ends up in his house as his adopted daughter. Before that she was with the Gales. They had brought her back from an orphanage, decided she was a jinx, and treated her badly at every turn, while the whole household doted on the girl they had adopted. Candice is a child who brings luck to whoever keeps her. In the Smith house the trouble that had been closing in turns around, Simon's wife wakes after a long time unconscious, and the son who went missing three years earlier is found.
