To celebrate their good fortune, Celia is throwing a party, an elegant and joyous evening for their family, friends, neighbours and business contacts.
With the preparations in full swing, Celia receives a letter from a man claiming to be her son, David, the child she gave up at birth. Celia impulsively invites David to the party - and therefore to stay - without consulting Dom.
With he arrives with an unexpected companion in tow, Celia's life is thrown into disarray.
By the end of the Summer, her marriage, her sense of family and her equilibrium will all have been challenged, and life will never be the same again.
