Every month they gather over good food and wine to discuss their favorite books: six very different women-not quite friends, not quite strangers. Enid is a successful psychiatrist, brilliant yet inexplicably dissatisfied; Donna, torn between two lovers, dreams of family but fears commitment; Rina's destructive fantasies may be her downfall; Pat and Hedy are sisters as dissimilar as they are competitive; and Connie is the envy of all her friends with the perfect career, the perfect family, the perfect life. Brought together by their love of literature, they share a deep understanding of one another?or so they think.

Then Connie, the woman seemingly so happy, announces that she is divorcing her husband for reasons she refuses to share.

The ensuing drama that unfolds forces each woman to explore the secrets shaping and burdening her life as they speculate about what could have happened-and what, in their own circumstances, would constitute the ultimate betrayal.
