Despite being the illegitimate daughter of a prince, Gillian Dryden is happily ignorant of all social graces. After growing up wild in Italy, Gillian has been ordered home to England to find a suitable husband. And Charles Valentine Penley, the excessively proper, distractingly handsome Duke of Leverton, has agreed to help transform her from a willful tomboy to a blushing debutante.
