"Since there is no hope of my securing an eligible partner due to sad lack of looks, I am running away."

So writes the sixth of the famous Armitage sisters. For how could colorless Frederica withstand a season's scrutiny after the five beauties before her had married so magnificently? Disguised as a chambermaid, Freddie finds her way into the household of the fashionable Duke of Pembury. That wild gentleman is soon onto her tricks and finds himself escorting the lady to London. Once on the marriage mart, the five sisters preen and prim the youngest until Freddie can't even recognize herself. They do not seem to notice that a certain gentleman's attention has Freddie blooming, and that perhaps she was not fated to be plain—or unmarried—after all.
