There are many books about Muhammad Ali, but none like Stuart Cosgrove's Cassius X ... The book is a deeply personal look at one of 'The Greatest' public figures of the last one hundred years and is a model of how biographies of African Americans should be written

Fascinating ... a different take on its subject, like a wayward B-side of a highly familiar tune

A vivid, knowing close-up of a crucial year in the life of boxing’s most iconic figure

Stuart Cosgrove's deep research and very human storytelling highlights how black music lit up the Sixties against a backdrop of political turmoil - and how Cassius Clay began his remarkable transformation into Muhammad Ali winning the world heavyweight title from scratch three times in the process

An engrossing and revelatory read.. and a great playlist. You do not have to be a fan of boxing or soul music to love this book

A benediction of a book about the early years of the sporting deity. Cassius X is a unique take – no easy feat when faced with an athlete who has been embalmed in books over the decades

Equivalent to a biopic which portrays the fast-moving 1960s social, political and cultural scene and gives a fascinating insight into a lesser-known part of the legendary champion's life

A riveting profile of one of the world’s greatest sportsmen and the world he moved in

No ordinary tale of the life of The Greatest. Tells the story of the many social forces that shaped the life of the former world champion
