Miranda Barnes is beautiful, young and rich, but she stands to lose her very large inheritance if she doesn't marry the spoiled, libertine son of her father's closest business partner, the obnoxious, womanizer Oliver Renaud.
Both unhappy with being forced together, Oliver keeps making things worse and Miranda keeps getting revenge--two people couldn't be more poorly suited for one another.
On their own in London, they are content to have an open marriage, until they discover they're in love for the first time in their lives--just not with each other!
