Post-Traumatic Stress Disorder goes far beyond the horrors of war and is an inescapable part of all our lives; at any given moment, more than six million Americans are suffering with PTSD. Combining patient stories, interviews with scientists, and her experiences on the frontlines of PTSD, psychiatrist Shaili Jain demonstrates how it interferes with one's capacity to love, create, and work—incapacity brought on by an interplay between biology, genetics, and environment. Offering hope, Jain highlights how care is becoming more available to sufferers through peer support programs and technology, and by identifying those who are most vulnerable to developing PTSD, it may even be possible to prevent its onset.
