Jonathan Eig, one of America's best storytellers, conducted more than six hundred interviews with more than two hundred people, one way or another related to the sports legend, while working on this book, and raised many archival sources. All this made it possible to recreate a reliable, full of details story in which Ali is revealed from a new, unexpected side. As if a time machine, she will transport you as close as possible to the young Cassius Clay, his mother, father and many others; to the fighter for justice, the idol of youth and the favorite of women - Muhammad Ali.
