After 25 years of caring for children, first as a nurse, then as a pediatrician, Carolyn Roy-Bornstein finds herself on the other side of the stretcher when her 17-year-old son Neil is hit by a teenage drunk driver while walking his girlfriend Trista home after a study date. Trista did not survive her injuries. Neil carries his with him to this day. Gratitude for her son’s survival ultimately gives way to grief. While initially told Neil’s only injury was a broken leg, Roy-Bornstein quickly finds herself riding in the front seat of an ambulance transporting her son to the ICU at Brigham and Women’s Hospital in Boston; his brain is bleeding. Roy-Bornstein is now not the patient’s doctor or nurse but his mom. The world she so easily navigates in a white uniform or a white coat now must be traversed, understood, and dealt with from the perspective of a parent. There are many dividing lines in this story. The line that divides this family’s life in two: the events that occurred before the crash and those that came tumbling and faltering in its wake. The line that separates grief from gratitude: gratitude that her son is alive and as whole as he is; grief for his loss of memory and changed personality and for having his whole world shattered in an instant. The line that separates the world Roy-Bornstein knew so well as a doctor from the new one she must now navigate as the parent of a trauma victim. In these pages she explores all of these boundaries: between then and now, grief and gratitude, before and after, us and them. Her many years as a "medical insider" bring her story authenticity and detail, while her newcomer status as the parent of a trauma victim add poignancy and warmth in this first memoir.
