On a Night Like This — Ellen Sussman

Blair Clemens is a struggling single mother with a teenage daughter, a job as a chef, and a tragic secret that will test all of her emotional resources. Luke Bellingham has fulfilled his early promise and is one the country's most acclaimed screenwriters. Luke and Blair haven't laid eyes on each other for decades, but back in the 1960s, they went to the same West Coast high school.

Now, for a class reunion, Luke impulsively contacts a woman who has always intrigued him. And before she knows what hit her, Blair is faced with the decision of her lifetime: what to do when the right man comes along...but at the wrong time.
