In this collection of "clinical tales," to use Oliver Sacks' term, Sue Hall, an experienced neonatologist who spent some years as a social worker before medical school, tells a remarkable range of stories about newborns in the NICU and their parents.  As memoir, the stories record moments in a life full of other people's traumas, disappointments, anxieties, and hard-won triumphs where her job has been to hold steady, find a balance point between professionalism and empathy as young parents go through one of the hardest kinds of loss.  Each story is told with clarity and grace, sketching the characters deftly and offering useful medical information along the way on the assumption that many who read the book will do so because they are facing similar challenges and decisions.  Each story is followed by a two- to three-page "Note" giving more precise medical background and offering further resources for those who have particular interest in the kind of case it was.
