I read this book in 1981...it is a book that I still recommend to people. Extremly powerful a book capable of moving the most jaded. I am now a Social Studies teacher and assign it to my students as a historical record as well as book of inspiration, and perserverance.. To read an experience such as Martin Grays and how he still have the courage to continue on is testament to the human spirit.
