The outrageous Isabella, the youngest of four daughters of a penny-pinched baron, decides that, to alleviate her father’s purse, she will not make her debut in society as her sisters, the Halverston Belles, have done, but she will become a governess and make her own living. Her family, while used to her untamed tongue and opinionated pronouncements, are nonetheless dismayed by her announcement. To change her mind, they enlist the help of Lord Oliver Westminster, the wealthy younger son of a marquess, who has long been regarded a member of the Halverston family. Lord Oliver has his own reasons for setting about this task, but he is well aware that Isabella has not a single thought of him as a potential husband. Can he persuade her to give up her firmly-set notions before her disregard for the ways of Society damages more than her own future?
