'My beautiful girls. If you've read this, you'll know it contains some — not all, but some — of the things I want my daughters to know. And the greatest of these is love ...' 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. And teenage Hannah, stumbling her way towards adulthood. Barbara's answer is to write each daughter a letter, finally expressing the hopes, fears, dreams and secrets she couldn't always voice. These words will touch the girls in different — sometimes shocking — ways, unlocking emotions and passions to set them on their own journey of discovery through life.
