Lauren, mother of twins, wakes up one morning to her Wife Alarm Bells sounding. She sleuths on her husband’s phone and stumbles on a dirty secret that explodes her marriage. Madeline has it all—a penthouse apartment, a perfect daughter, and no-strings-attached romps with handsome men. But when she learns she might lose her child to her ex in England, it stirs up a decades-old personal tragedy. Sophie, with too much FOMO and never enough money, obsesses over her ex-husband’s Family 2.0—all while keeping her true desires hidden, even from herself. It starts as a joke during a tipsy night out, as Lauren, Madeline, and Sophie rail against everything wives do for free. Let’s build an app that monetizes the mental load. And maybe revenge on our exes in the process. Soon, the Wife App is born, and before long, it’s the fastest growing start-up in New York City. But then life intervenes. Love intervenes. Ex-husbands intervene. And the consequences are bigger than anything Lauren, Madeline, or Sophie could have expected. Carolyn Mackler marks her debut into adult fiction with a rollercoaster ride of revenge and redemption that is at once a send-up of modern marriage and a celebration of female friendship and love in all forms.
