For many soldiers, there is a war after the war. After experiencing the horrifying aspects of war, many soldiers are afflicted with Post Traumatic Stress Disorder, termed by some as "cancer of the soul". In Angel of Death, John Blehm tells of his wartime experiences and the thirty-eight years he has been suffering from PTSD. The book is a combination of an original work, Death Angel, and an additional nine chapters written ten years after the first edition. These chapters chronicle Blehm's journey with PTSD and the way he found peace through his faith in God. Angel of Death is written with the help of his wife, Karen, and is for soldiers and their families who wonder if they will ever reconnect with society. It is written for those who are asked to lay down their weapons and return to civilian life but seem to have lost the necessary pieces for this transition. It is a message of hope for those who have lost it and cannot seem to come back, and it is the testimony of a tortured soul who has found peace within.
