"Invisible" is real life: flashbacks, nightmares, and anger alongside friendship, love, and recovery. Bill Blaylock suffered from post-traumatic stress disorder for years. The ultimate revelation of his malady explained everything: the 39 jobs, the failed marriage, and the fear that prompted him to check the perimeter of his home every night-- even forty years after the war. The book "Invisible: PTSD's Stealth Attack on a Vietnam Veteran" is comfort for every soldier, every wife, every family, and every victim of a stealth disease that wreaks havoc with its gruesome memories, guilt, and loneliness. Despite the horrific experiences, Bill Blaylock has learned to cherish God, family, friends, and country.
