Most Americans are now familiar with PTSD (post-traumatic stress disorder) and its prevalence among troops. In this groundbreaking new book, David Wood examines the far more pervasive yet less understood experience of those we send to war: moral injury, the violation of our fundamental values of right and wrong that so often occurs in the impossible moral dilemmas of modern conflict. It is a call to listen intently to our newest generation of veterans, and to ponder the inevitable human costs of putting American "boots on the ground" as new wars approach. --
