In 2007–08, Dr. Ray Wiss, a former infantry officer, served with the Canadian Forces at forward operating bases in Khandahar's Panjwayi valley, the area experiencing the most intense combat in Afghanistan. He spent more time in the combat area than any other Canadian physician, and his successful first book, FOB Doc, was the diary of his time “outside the wire” during that tour of duty.Captain Wiss's experience in Afghanistan convinced him that this conflict was a rare example of a moral war. When asked to return for an even longer tour of duty in the combat zone, he readily agreed. Once again, he kept a diary, writing with passion about the efforts, sacrifices and achievements of those Canadians who served with such distinction. Illustrated with over 100 colour photographs, A Line in the Sand tells us about virtually every kind of soldier fighting in Afghanistan: the bomb technician, the engineer, the combat medic, the “grunt” as well as about the Afghans, from whom we are seemingly so different yet with whom we share so much. It is an impassioned insider’s view of the war in Afghanistan and a convincing testament to why it matters.
