Tyson by Ellis Cashmore. It is not only about Tyson but also a study about how society percieved him. It is written by a sports psychartrist. If u want to know more, just pm me.
"The Inner Ring" by Rudy Gonzalez tyson's limo drive and the only person in the world with him every day of his from 86/91 except the day he met Desiree. This book gives you the insight on his early days of being a champion and how out of control he was.
Bad Intentions is a great book about his early career. My favorite recent one is Iron Mike: A Mike Tyson Reader. It has a ton of stories in there all the way up to right before the end of his career. EDIT: You can get the last book I mentioned used on Amazon for 95 cents.
