In reply to broken spectre:
I picked it up on a whim and it was well worth reading. As a middle class white guy myself, it's a rare prison tale that is written by someone I can relate to. It's pretty depressing in it's assessment of the prison system and the chances of anyone without his privileges to escape it.
I loved Ivan Denisovich, must read it again sometime. The Long Walk is the Polish guy who escaped from Siberia and saw the Yeti, yes? Fun, but a bit silly claiming it as a true story.
