Having missed much of her children's lives while she built a home-furnishings empire, Olivia Grayson arranges a family vacation in the Mediterranean in the hopes of rekindling ties only to confront painful interpersonal dynamics and unexpected revelations.

As a way of making up to them for time lost, Olivia spends months every year planning a lavish holiday that everyone in her family will enjoy. This summer she has arranged a dream trip in the Mediterranean on a luxurious yacht, which she hopes will be the most memorable vacation of all. Her lavish gesture every year expresses her love for them, and regret at all the important times she missed during her children’s younger years. Her younger daughter, Cassie, a hip London music producer, refuses the invitation altogether, as she does every year. Her older daughter, Liz, lives in her mother’s shadow, with a terror of failure as she tries to recapture her dream of being a writer. And her sons, John and Phillip, work for Olivia, for better or worse, with wives who wish they didn’t. In the splendor of the Riviera, this should be a summer to remember, with Olivia’s children, grandchildren, and daughters-in-law on board. But as with any family gathering, there are always surprises, and no matter how glamorous the setting things don’t always turn out as ones hopes. Family dynamics are complicated, old disappointments die hard, and as forgiveness and surprising revelations enter into it, new bonds are formed, and the future takes on a brighter hue. And one by one, with life’s irony, Olivia’s children find themselves committing the same “sins” for which they blamed their mother for so many years. It is a summer of compassion, important lessons, and truth.
