“A masterpiece... grimly tragic on one page, laugh-out-loud funny on the next, and unrelentingly vulgar and foul-mouthed. Reading Tyson's memoir is like watching a Charles Dickens street urchin grow up to join Hunter S. Thompson on a narcotics-filled road trip - with the ensuing antics captured on video by assorted paparazzi.” (Hector Tobar, Los Angeles Times)

“Undisputed Truth is raw, powerful and disturbing - a head-spinning take on Mr. Tyson's life…Unlike other sports memoirists, he doesn't pull punches, offering up slashing comments on people who were once close to him. His narrative reminds us of just how far he has come from his rough beginnings, and, in a way, how close he remains to them. He had a punch like a thunderbolt from Zeus, but there have been a lot of big bangers in boxing; Mike Tyson's came with a pulsating story line like few others.” (Gordon Marino, Wall Street Journal)

“Parts of [Undisputed Truth] read like a real-life Tarantino movie. Parts read like a Tom Wolfe-ian tour of wildly divergent worlds: from the slums of Brooklyn to the high life in Las Vegas to the isolation of prison…. Mr. Tyson’s idiosyncratic voice comes through clearly on the page here - not just his mix of profane street talk and 12-step recovery language, cinematic descriptions of individual fights and philosophical musings, but also his biting humor and fondness for literary and historical references that run the gamut from Alexandre Dumas to Tolstoy to Lenin to Tennessee Williams…. A genuine effort by a troubled soul to gain some understanding of the long, strange journey that has been his life.” (Michiko Kakutani, The New York Times)
