Lady Justine is willing to trade her good name, her reputation and her place in London's gossip-hungry ton to secure her father's release from prison. But when the notorious Duke of Bradford counters her offer with a proposal of marriage, the stakes grow higher still. For while the smoldering lord is famous for his conquests, the man is oblivious to both her devotion and her charms. And Justine is soon afraid she has wagered all for naught....

A little red book by an unknown author.

Three unlikely couples...and scandal galore.
