*THE INCREDIBLE COMEBACK STORY OF THE 2025 MOTOGP WORLD CHAMPION*

Marc Márquez is the apex predator of the MotoGP world: arguably the greatest motorcycle racer who ever lived, he is a nine-time world champion. He is the man who dethroned Valentino Rossi, and who changed the sport of MotoGP forever.

Márquez's hyper aggressive riding style has made him many enemies, his epic championship battle with Valentino Rossi in 2015 led to one of the most controversial moments in the history of MotoGP and his closely-fought battle with his brother, Alex, for the 2025 title capped off an astonishing sporting comeback story.

But his story off the track is just as incredible: devastating accidents, surgeries and recoveries, racing on despite a diagnosis that left him knowing one more head injury could leave him blind. His self-admittedly ruthless personality and desire to win make him an explosive, dominant and at times controversial character.

Told by bestselling author Stuart Barker, with the insight of rivals, team members, pundits, managers and many close to his story, this is the a story of pure sporting theatre and white-knuckle speed twinned with real human drama. Marc Marquez: Everything or Nothing is the Márquez told in full for the very first time.
