Mark your calendar. It's the Christmas Cookie Club! Every year on the first Monday of December, Marnie and her twelve closest girlfriends gather in the evening with batches of beautifully wrapped homemade cookies. Everyone has to bring a dish, a bottle of wine, and their stories. This year, the stories are especially important. Marnie's oldest daughter has a risky pregnancy. Will she find out tonight how "that" story might end? Jeannie's father is having an affair with her best friend. Who else knew about the betrayal, and how can that be forgiven or forgotten, even among old friends such as these? Rosie's husband doesn't want children, and she has to decide, very soon, whether or not that's a deal breaker for the marriage. Taylor's life is in financial freefall. Each woman, each friend has a story to tell, and they are all interwoven, just as their lives are.
