Born in a brothel, Ruth doesn't expect much for herself beyond abuse. While her sister's beauty affords a certain degree of comfort, Ruth's harsh looks set her on a path of drudgery. That is until she meets pugilist patron George Dryer and discovers her true calling--fighting bare knuckles in the prize rings of Bristol. Manor-born Charlotte has a different cross to bear. Scarred by smallpox, stifled by her social and romantic options, and trapped in twisted power games with her wastrel brother, she is desperate for an escape. After a disastrous, life-changing fight sidelines Ruth, the two women meet, and it alters the perspectives of both of them.
