Can a marriage of convenience turn into love?

Caroline does not believe so especially when her husband, Sir Theodore, is as stubbornly traditional and she herself is forward-thinking.
With the assistance of a magical charm given to her by her fairy godmother, Caroline hopes to, at least, change his mind about letting her administer her own fortune.
But she doesn't expect the tendrils of affection that develop for her well-meaning husband – nor does she expect to have to track down someone intent on murdering him.

Will Caroline discover the killer before its too late to tell Theo that she loves him?
