Sophia is a secretary struggling with daily temptation as a parade of lovely, unavailable men (and their haughty female partners) pass her desk at the secretive law firm where she works. One male client stands out from all the others: James Goodman, who is contracted to the super-rich Isobel Pettifer. Sophia can't get James out of her mind.
She wouldn't feel so tempted if only her prissy husband Philip was able to satisfy her, or express his own needs. But even his attempt to explain himself by giving her a book brings more confusion than clarity.
Sophia takes refuge in a fantasy life that invariably features James ... until she inadvertently triggers a chain of events that will push her away from fantasy and into discovering who she really is -- and what that means for both the men in her life.
