Pleasure's Daughter by Sedalia Johnson
It's 1750. Orphaned Amelia, headstrong and voluptuous, goes to live with wealthy relatives. During the journey she meets the exciting, untrustworthy Marquis of Beechwood. She manages to escape his clutches only to find he is a good friend of her Aunt and Uncle. Although aroused by him, she flees his relentless pursuit, taking up residence in a Covent Garden establishment dedicated to pleasure. When the marquis catches up with her, Amelia is only too happy to demonstrate her new-found disciplinary skills.
