Gwyn Huntington knows how to throw a party. And Hunt Hall, her postcard-perfect Victorian home in Montauk at the easternmost tip of Long Island, is no stranger to celebrations. But on the morning of her thirty-fifth wedding anniversary, she's putting finishing touches on the last party she'll host there. The last time she'll see Hunt Hall abuzz with caterers and bartenders. The last time she'll preside over a gathering of beautiful friends swaying in candlelight. The last time sheï¿½ll fully play the role of wife: Mrs. Thomas Huntington. Divorce parties have become commonplace, if not fashionable, in Montauk. But Gwyn is determined that hers will be different.
Just over one hundred miles away on the same morning, Maggie Mackenzie sits on the floor of her Brooklyn apartment attempting to organize her new life. A former travel writer, she's fallen in love with a wonderful man, gotten engaged, and is planning to start a business with him. Today is also the day she'll meet her fiance's parents for the first time. Sheï¿½s feeling particularly uneasy about the occasion surrounding her first meeting with Nate's family.
The Divorce Party takes us into the lives of these two women at opposite ends of marriage. For all the differences between them--distance, privilege, age--Gwyn and Maggie have one thing in common: each has found herself at a crossroads. Gwyn has been preparing for this day, the last predictable day before an uncertain future. But even though she's had time to come to terms with her divorce, she still can't quite bring herself to believe her marriage is really over. How can she move on when her marriage has defined who she is for the last thirty-five years? And for Maggie, the trip to Montauk shakes the foundation of her relationship with Nate and dredges up feelings she's spent her life trying to avoid.
In the end, each woman must look inside herself to answer the questions that will define her life from this moment on. How much work is it worth to keep two people together? And at what point is it time to let go?
