...The Long Walk, by Slavomir Rawicz. Short version: Young Polish army officer in early WW2 sent to Soviet kangaroo court and then hard labor in Siberia. He finds a small crew and escapes, traveling south through Siberia, Soviet Union, Gobi desert, Himalayan mountains, arriving in India where they are picked up by a passing British patrol. The only tools they had were an axe and a knife. Did I mention no canteen? Through the Gobi desert??!! It's a quick and inspiring read. I am stunned by this story. Everytime I think I'm tired, or had a bad day, I am reminded of this. Do not delay. Get the book. I've already passed my copy to a friend. Everyone deserves to read it.
