Dancing With the Gull. Revenge of the Wallflowers, #14

Lady Penelope Barshaw is known as a shy, sweet girl among the ton. She's perfectly happy fading into the background of balls and supper parties because Society makes her feel quite awkward. Her reticence is disturbed, however, as she sees a number of viragos lined up to entrap a gentleman. Lord Henry Greer, Henny to his friends, is known as a capital chap. He stays close to his best friends, however, because the vagaries of Society are a mystery to him.
Nothing ever works quite the way it is supposed to, and now that his parents expect him to marry, he finds it impossible to determine a suitable wife.
