When a group of friends in Mason, Missouri decide to start a monthly supper club, they get more than they bargained for. Instead of sharing recipes, they begin sharing secrets. When Iris Winters and Maddy Harris are invited to the club, they find that it's just what each of them needs. Iris hasn't yet told anyone about the unlikely man who has captured her attention, and Maddy has come back home to escape a problem too big for her to confront.
