London, 1819. Richard, Marquess of Devon is satisfied with his ton marriage. His wife of five months, Lady Eugenia Devon, thought she was, too, until she found the book. Their marriage is one of respect and affection, with no messy entanglements such as love. Devon's upbringing impressed upon him that gentlemen slake their baser needs on a mistress, not their gently bred wives. However, once married, he was no longer comfortable bedding a woman other Eugenia. When she stumbles onto a naughty book, she begins a campaign to change the rules. Lady Eugenia wants her very proper husband to fall in love with her. But her much changed and undeniably wicked behavior might inadvertently drive her confused husband to ponder the unthinkable-his perfect Lady has taken a lover. But the only man Eugenia only wants is her husband. The book can bring sizzling desire to the marriage or it might cause an explosion. Contains mature themes.
