Query: A great read!

I loved this book! It read very quickly, and I soon became engrossed in the details of Doc's life. At times this book was very funny, and at times harrowing. Moreover, Parsons shines a much-needed light on conditions in our nation's prisons. He must have done a lot of research because I really got the feeling he was telling it like it was. Good story, important subject: I highly recommend it.
