I have never read the printed version so I cannot really comment, but the narration on this audio edition is excellent.
I honestly couldn't specify one particular part of the book, the whole story is gripping. From Tyson's childhood memories, training, fights and his battle with women, drugs & alcohol. A fantastic listen!
As I said above, it's difficult to identify specific parts, however, the accounts of his relationship with Cus D'Amato and how he built Tyson both physically and, probably even more so mentally, into the fighter who became the youngest heavyweight champion of the world was brilliant listen.
Both! Tyson really has lead an eventful life and this book gives a "warts & all" account of it. He tells the stories of his off the wall life episodes and gives honest explanations of his mental state throughout. It has amusing and extremely moving parts.
Brilliant narration and an excellent listen!
