The Devilish Trollop by Merry Farmer

Summer parties were made for mischief….

Miss Felicity Murdoch may be an heiress with a large fortune attached to her, but she is as far from the genteel, respectable sort of lady that most men of the ton would want to marry. Her only hope to find a titled husband–as her father has insisted she must–is to deport herself well at her friend, Lady Caroline Herrington’s, summer house party. But almost from the start, Felicity is in trouble.
Lord Sullivan Whitlock is desperate to find a bride with money to save his family’s failing estate. He has never been adept in the ways of society, though, and doesn’t know how to woo honorable women. It is love at first sight when he spies Felicity across the room. She is the wickedest wallflower he has ever known.
But what starts out as a fun and passionate flirtation runs into trouble when the nefarious Lord Cunningham seeks to split the two lovers apart. Will the truth win out over deception? Will Felicity and Sully, not to mention Lord Cunningham, get what they deserve?
