Sir Gareth Ludlow is just about ready to settle for marriage with Lady Hester, a plain woman who falls below his standards (according to his sister). Despite her protests, however, Gareth sets out to propose marriage.
Along the way, he encounters young Amanda wandering unattended. Honor-bound to restore her to her family, the gallant Sir Ludlow finds he has more than he bargained for with his young charge and her runaway imagination.
