How would you say goodbye to those you love most in the world? Barbara must say a final farewell to her four daughters. But how can she find the words? And how can she leave them when they each have so much growing up to do? There's commitment-phobic Lisa. Brittle, unhappily married Jennifer. Free-spirited traveller Amanda.
