Book excerpt: “An essential book” on PTSD, an all-too-common condition in both military veterans and civilians (The New York Times Book Review). Post-traumatic stress disorder afflicts as many as 30 percent of those who have experienced twenty-first-century combat—but it is not confined to soldiers. Countless ordinary Americans also suffer from PTSD, following incidences of abuse, crime, natural disasters, accidents, or other trauma—yet in many cases their symptoms are still shrouded in mystery, secrecy, and shame. This “compulsively readable” study takes an in-depth look at the subject (Los Angeles Times). Written by a war correspondent and former Marine with firsthand experience of this disorder, and drawing on interviews with individuals living with PTSD, it forays into the scientific, literary, and cultural history of the illness. Using a rich blend of reporting and memoir, The Evil Hours is a moving work that will speak not only to those with the condition and to their loved ones, but also to all of us struggling to make sense of an anxious and uncertain time.
