What does the devil do when he is invited to a wedding and the invitation says, plus guest?

Lost in his thoughts about the possible choices, he takes a walk in the human world and happens upon one young woman that is the answer to his question. As always, his life is about deals. All that could be asked for can be given, for the right price. But his offer is one of simplicity, save her failing business and in return be his date for the wedding. All he has to do is convince her to accept his offer and with his charm and good looks, the devil knows he won't fail.

He never expected for the deal to last anything more than the few weeks that were ahead of them. Then again, he never expected to fall in love with her.

Unloved, unwanted. Two words that Sarah thought summed up her life. Unloved by her parents who favored her sister over her, unwanted even after their death. All that she has in this world is the fast depleting inheritance and her little restaurant that is failing. Despite being a brief walk from one of New York's best tourist attractions, she still fails to make a profit. She knows that soon she'll be sleeping in the restaurant to cut her expenses. So when one man offers her a deal that seems too good to be true, she is obviously hesitant. But being a failure was never in Sarah's future, she was desperate to prove her nasty sister wrong. Committing to the deal of a lifetime could cost Sarah so little if she accepts.

One little walk through the bustling city of New York will alter their worlds and their lives forever, entwining them in ways they never thought possible.
