On their 35th anniversary, Gwyn Huntington and her husband Thomas have invited friends and family to their Montauk home. Instead of celebrating their decades-long love, they are toasting their divorce. This also marks the weekend that their son brings home his fiancée, Maggie Mackenzie, for the first time. Maggie thought she was joining a perfect family, but she is about to reckon with some uncomfortable truths about the man she wants to marry.
A multi-generational story about what it means to share a life with someone, The Divorce Party brings us two immensely appealing women: Gwyn who is stumbling upon the end of her marriage, and Maggie, her future-daughter-in-law, who is trying to navigate the beginning of hers. With emotional candor and surprising humor, these two women find themselves trying to answer the same questions: Can you ever really know someone? When should you fight for the person you love most, and when should you begin to let him go?
