To become a countess...
Rule #1: A lady does not attempt to come out in London society disguised as her deceased half-sister.
Rule #2: A lady does not become enamored of her guardian; even though his masterful kisses and whispered words of affection tempt her beyond all endurance.
Rule #3: A lady may not climb barefoot from her bedroom on a rose trellis, nor engage in fisticuffs with riff-raff in order to rescue street urchins.
Rule #4: No matter how impossible the odds, a lady always gives her hand and her heart — though not necessarily in that order — to the one man who sees her as she truly is and loves her despite her flagrant disobedience of every one of the . . . Rules for a Lady.
