It was supposed to be a season in France, but then she decided not to go home.

Diane Talbot is an American in Paris and desperately wants to stay that way. Instead of returning to Woollett, New York, she and her sister didn't get on the boat. Now, nearly a year later, their father's fiancée and her stepson—at Daddy's behest—have come to Paris to bring them home. When they surprise Diane in a compromising situation with French party boy Guillaume Allard, she improvises and claims they're engaged. 

It's the perfect plan. As long as she can convince her family that she's getting married and has established herself in Paris, they can't take her home. The best part is that Diane won't really have to get married—not to the man her father wants or to Guillaume.

Handsome and charming Guillaume barely knows Diane. But she's fun, and he owes her a favor. He goes along with the fake engagement, but that's a decision he soon regrets. 

As Diane and Guillaume spend more time together, the ruse gets harder to perpetuate, and her family gets more involved. Soon, this perfect solution is far trickier than anticipated, and their feelings for each other have grown so complicated that it can only be love. Ultimately, they're forced to face an impossible obstacle to their happily ever after: he wants a lifelong commitment, and she believes marriage is a trap best avoided.
