The Baroness of the Ring

Marianne Simpson has the appearance and manners of a refined lady, but every evening she steps into the arena of her uncle's traveling circus, and so far no opponent has managed to defeat the girl in an honest boxing match.
The handsome, noble, and arrogant St. John Powell, the Duke of Staunton, has earned the nickname Lord Impeccability from his detractors. The Duke despises circus performers and comedians, but he needs Marianne, for she is the only one capable of helping him rescue his younger brother from the clutches of the cruel and treacherous Baron Strickland.
