Lady Caroline Linford is horrified to discover her fiancé, the Marquis of Winchilsea, in the arms of another woman. Unfortunately, for the rest of Victorian society, this sort of extracurricular activity is par for the course for most men and certainly not reason enough cancel the upcoming wedding.

But Caroline is determined to make sure that the man she is to marry will desire only her, so she enlists the best teacher in the art of romance: London's most notorious rake, Braden Granville. As their passionate tutelage begins, sparks fly and the lines between teacher and student get increasingly blurred. Now there is just one last lesson to learn: on the subject of true love, the heart chooses its own unpredictable ways.
