The morning of her niece’s wedding, Margo Just drinks a double martini and contemplates the many mistakes she’s made in her fifty-odd years of life. Spending three decades in love with a wonderful but unattainable man is pretty high up on her list of missteps, as is a long line of unsuccessful love affairs accompanied by a seemingly endless supply of delicious cocktails. When the young bride flees—taking with her a family heirloom and leaving behind six hundred bewildered guests—her mother offers Margo fifty grand to retrieve her spoiled brat of a daughter and the invaluable property she stole. So, together with the bride’s jilted and justifiably crabby fiancé, Margo sets out in a borrowed 1955 red MG on a cross-country chase. Along the way, none of what she discovers will be quite what she expected. But it might be exactly what she’s been seeking all along.
