Lady Mercy likes her life neat and tidy. She prides herself on being practical—like her engagement to Viscount Grey, whose dark coloring coordinates very well with her favorite furnishings. But things start to get messy when her best friend abandons her fiance at the altar, leaving it up to Mercy to help the couple. There's just one problem. The jilted man is Rafe Hartley—Mercy's former husband.

Rafe has not forgiven Mercy for deserting him when they were seventeen. Their hasty marriage was declared void by law, but in his eyes the bossy little vixen was still his wife, even if the marriage lasted only a few hours. And Mercy "Silky Drawers" Danforthe still owes him a wedding night.
