Kitty Charing from the Regency Romance Cotillion by Georgette Heyer
To give you a bit of background information on Kitty's character, I will include a synopsis of the book:
Young Kitty Charing stands to inherit a vast fortune from her irascible great-uncle Matthew--provided she marries one of her cousins. Kitty is not wholly adverse to the plan, if the right nephew proposes. Unfortunately, Kitty has set her heart on Jack Westruther, a confirmed rake, who seems to have no inclination to marry her anytime soon. In an effort to make Jack jealous, and to see a little more of the world than her isolated life on her great-uncle's estate has afforded her, Kitty devises a plan. She convinces yet another of her cousins, the honourable Freddy Standen, to pretend to be engaged to her. Her plan would bring her to London on a visit to Freddy's family and (hopefully) render the elusive Mr Westruther madly jealous. Thus begins Cotillion, arguably the funniest, most charming of Georgette Heyer's many delightful Regency romances.
I could not help liking Kitty and how she grew as a character in the book. If you would like a character that escapes Regency Romance novel heroine pre-conceptions then read Cotillion for a breath of fresh air.
