Edward Warren is a prodigal son who left home after an irreparable fight with his father, Luke. Now Luke lies comatose in hospital, gravely injured in the same accident that has also injured Edward's younger sister Cara. Cara, 17, still holds a grudge against her brother, since his departure led to her parents' divorce. In the aftermath, she's lived with her father — an animal conservationist who became famous after living with a wild wolf pack in the Canadian wild. It is impossible for her to reconcile the still, broken man in the hospital bed with her vibrant, dynamic father. With Luke's chances for recovery dwindling, Cara wants to wait for a miracle. But Edward wants to terminate life support and donate his father's organs. Is he motivated by altruism, or revenge? And to what lengths will his sister go to stop him from making an irrevocable decision?
