How do you cope in a world without your mother?

When Barbara realizes time is running out, she writes letters to her four daughters, aware that they'll be facing the trials and triumphs of life without her at their side. But how can she leave them when they still have so much growing up to do?

Take Lisa, in her midthirties but incapable of making a commitment; or Jennifer, trapped in a stale marriage and buttoned up so tight she could burst. Twentysomething Amanda, the traveler, has always distanced herself from the rest of the family; and then there's Hannah, a teenage girl on the verge of womanhood about to be parted from the mother she adores.

But by drawing on the wisdom in Barbara's letters, the girls might just find a way to cope with their loss. And in coming to terms with their bereavement, can they also set themselves free to enjoy their lives with all the passion and love each deserves?
