When a group of friends in Mason, Missouri, decide to start a monthly supper club, they get more than they bargained for. The plan for congenial evenings--talking, laughing, and sharing recipes, homemade food, and wine--abruptly changes course one night when one of the women reveals something startlingly intimate. The supper club then becomes Confession Club, and the women gather weekly to share not only dinners but embarrassing misdeeds, deep insecurities, and long-held regrets.
