I have all the Dempsey books ever printed. None are great but if i had to pick one its A flame of pure fire
Loved this book. I finished it and within a week I started on it again. Highly recommend it for fans of dempsey and that era of boxing.
I havent read it but i heard the DEMPSEY Chronicles is a good book. From memory it focuses on the time when he was converted into a space robot and tried to regain the world heavyweight championship.
