The one thing Constance Martin wants most to avoid is a boring life. She walks her cat with a leash in Hyde Park and even called off her wedding at the altar to stop what would have been a monotonous marriage. So when an aristocratic friend comes into the store asking for help throwing over her fiancé, Constance is both sympathetic and eager for the excitement to come. What could be more fun than plotting ways to get a stuffy--but very handsome--earl to break an engagement?

Oliver Vincent, Earl of Southwyn, likes his orderly life of duty and logic. Everything's falling into place; all that's left is marrying the girl next door. Except the girl next door is increasingly reluctant. But marriage is a business deal, after all, and Oliver is determined to keep moving forward with the plan. If only he wasn't so distracted by her friend--a stunning woman best described as chaos incarnate. She thinks marriage should be an adventure, and he views it as a transaction. But Oliver can't seem to remember the downsides of falling when Constance is near. . .
