David Finkel is one of the truly great talents in journalism today. Even at The Washington Post, which has no shortage of talent, Finkel has stood out as an exceptional writer and chronicler, a master in particular of immersion-based, long-form reporting. Four years ago, in his first book, The Good Soldiers, Finkel provided a gripping narrative of the deployment in Iraq of a U.S. Army infantry battalion during the 2007-2008 surge. His new book, Thank You For Your Service (Sarah Crichton, $26), is a sequel that follows some of the same soldiers and their families in their difficult efforts to resume lives at home. This is a heartbreaking, haunting tale, filled with intimate portraits of ongoing struggles not just with physical injuries and mental wounds, but with isolation, loneliness, anger, and bewilderment.
