The Marrying Game — Kate Saunders

With a batty mother, a crumbling house and no education to speak of, the four Hasty girls aren't best equipped for the modern world. And when the death of their charming but useless father leaves them nothing but mountains of debt, drastic action is called for.

Luckily the eldest, Rufa -- already expert at making ends meet -- has a Plan. If their sole inheritance is their ravishing good looks then she and her sisters must put all thoughts of love out of their minds and Marry Money. And so, with her outrageously sexy sister Nancy, she sets off to blaze a trail through London society...
THE MARRYING GAME HAS BEGUN.
