Cinderella & The Playboy [EPUB ebook] 

The position: Hard-driving corporate powerhouse – and very confirmed bachelor – C. K. Tanner needs a "pretend" wife to help him convince an old-fashioned business associate that he’s a regular, reliable family man.The unwilling candidate: Abby Mc Grady, a beautiful, independent young woman who works in the mail room and detests almost everything about her arrogant, insufferable – but drop-dead-gorgeous – employer. The complication: The two of them are all wrong for each other – but they can’t keep their hands off each other, either. And the sparks flying are enough to make anybody want to turn a "temporary" partnership into the deal of a lifetime.
