The Duke's Hellion by Julia Sinclair

I don't think hellion is the proper word. Georgina is an independent and free thinking woman in Regency's times. Here we see a woman who has actually grown from her past mistakes and accepts who she is despite what her father or anyone else thinks about her. She cares about her family's reputation and that means keeping her past mistake a secret especially with a blackmailer hounding her. This gives Tristan and her a second chance, even when she thinks he will never forgive her. This story is well written and the mystery blackmailer was even a surprise for me.
