A good marriage lasts forever…until it doesn't. From the start, Lynn and Jamie Prosper were one of those couples who seem meant to be-so content with each other that they barely notice the rest of the world nodding approvingly at their wedded bliss. But sometimes, even in the very best of marriages, all it takes is a mischievous outsider to bring the perfect couple toppling off the top of the wedding cake… True, Jamie has been working so hard and traveling so much as a young lawyer that he hardly has enough energy to show his devotion. Not that Lynn, a junior museum curator, has any reason to question it. But when Lynn's old college friend turns up at a cocktail party, chinks in their marriage's previously unassailable armor start to show. Suddenly, without meaning to, Lynn and Jamie have both acquired divorce lawyers. And those benevolent onlookers-meddling in-laws and competitive friends alike-eagerly bear witness to each new misstep. Is love really enough to make a marriage last?
