From the author of "The Good Soldiers," David Finkel writes with tremendous compassion, not just about soldiers but about their wives and children. Where do soldiers belong after their homecoming? Is it reasonable, or even possible, to expect them to rejoin their communities as if nothing has happened? And in moments of hardship, who can soldiers turn to if they feel alienated by the world they once lived in? These are the questions Finkel faces as he revisits the brave but shaken men of the US 2-16 Infantry Battalion.
