After their crazy father killed their mother, sixteen-year-old Francis Dominique became solely responsible for the welfare of her two young sisters. The colony of St. Antoni is a rough place; a woman needs to be smart and tough enough to protect, feed and clothe herself or find a man to do it for her. Francis opted for the first choice, and went to work for the Enforcers, St. Antoni’s elite law enforcement bureau. She tries desperately to keep her mind on her work and not dream about her boss, the handsome, devil-may-care Hercule Jones.
When she is drafted into taking part in an investigation, she finds herself embroiled up to her neck trying to identify the outlaws robbing the trains connecting St. Antoni’s City States. Then the investigation turns dangerous and personal problems begin piling up. Her father escapes from the Asylum for the criminally insane, and a lawyer with a custody writ arrives intending to drag her and her sisters to Copper City to live with grandparents who have ignored their existence until now. Can Francis keep her sisters safe and catch the outlaws without being killed herself?
