What I Did For a Duke

Heroine was a tramp and unlikable. Madly in love with a guy her whole life and sleeping with another man within days. No constancy. No HEA could be implied. She would be playing him false before the year was out. Author went out of the way to show that the only thing they had in common was passion. Heroine turned out o be just like her brother and her brother's tramp. Gross and unromantic.
