The Long Walk: A Story of War and the Life That Follows (Doubleday, $25.95) is Brian Castner’s nonfictional portrayal of the toll war exacts on the men and women who are fighting it. Castner served three tours of duty in the Middle East, two of them as the commander of an Explosive Ordnance Disposal unit in Iraq. When he returned home to his wife and family, he began a struggle with a no less insidious foe, an unshakable feeling of fear and confusion and survivor’s guilt that he terms The Crazy. “. . . a powerful, intimate, disturbing look at the ways that war can infect the life of a soldier.”—Christian Science Monitor.
