Celia Grey appears to have the perfect life: married to Dominic, the man of her dreams, and living on a glorious, thriving vineyard in the south of France. To celebrate their good fortune, she decides to throw a huge party. When she is contacted by a stranger who claims to be her long-lost son, David, the newborn she gave up at twenty and has never spoken of since, Celia impulsively invites him for the weekend of celebrations - without mentioning it to her husband. Despite his surprise, Dominic graciously welcomes David and his unexpected companion - but secretly he harbours doubts. Is David really Celia's son? And who is the mysterious young woman travelling with him? Only Celia can decide how far she will go to hold everything together, to keep her perfect life from unravelling.
