Hey guys. I am stuck on finding this book about three couples who win trips to Paris. The first part is about a divorced mother with kids who goes to work on a radio station, and then falls in love with her boss's son. The books thinks that the woman and the father have a thing going on, and works to win her over. The second book is about a woman who lives in the country side who has kids with her best friend when she was young, but he didn't know about it. When he finds her, he flus back to where he was from and finds that he has twins named Ben and Jerry. They eventually fall in love and stay together. The last book is about a woman named Daisy who owned an airplane company. She had a rival who had a company right next to her, and was always trying to get with her. She is always resisting, but one day they go together and he asks her to marry her in the end. They fly off to Paris in the airplane in the end.

Is this perhaps Paris or Bust! by Kate Hoffmann? There are 3 stories and the plots and character names seem to match up. Here is the synopsis:

A trio of romantic comedies that will tickle readers! When Family Travel magazine sponsors a Mother of the Year contest with a trip to Paris and a shopping spree as the prize, the response is overwhelming! And the laughs are outrageous as three women discover that being finalists isn't the most excitement they'll ever have...falling in love is!

You are a lifesaver!!!! I have been trying to find this book for years!

So glad to hear that's the one!
