A lady will not smoke cheroot. She does not ride astride. She will not fence or go to duels. She does not fireplace a pistol, and she never gambles at a gentlemen’s golf club.

Female Calpurnia Hartwell has always followed the rules, rules which have left her unmarried-and more than a little unsatisfied. And so she’s vowed to break the rules and live the life span of satisfaction she’s been lacking.

But to dance every dance, to grab a midnight kiss-to do those things, Callie will need a ready partner. Someone who knows everything about rule-breaking. Someone like Gabriel St. John, the Marquess of Ralston-charming and devastatingly good-looking, his wicked popularity matched just by his sinful smile.

If she’s not careful, she’ll break the main rule of all-the one which says that pleasure-seekers shouldn’t fall hopelessly, desperately in love .
