Winning the Wallflower

It could only happen in a fairy tale.
Lady Lucy Towerton:
Plain and tall. (According to the lady herself.)
Titled and irreproachably proper. (According to her fiancé.)
Until, overnight, she becomes
Lady Lucy Towerton:
Heiress. (Thanks to an aged aunt’s bequest.)
Belle of the ball. (So say the fortune hunters of the ton.)
In charge of her own destiny (finally!), Lucy breaks her engagement and makes up her mind never to be proper again…
