This edition includes the account of Alex's El Capitan climb, subject of the Oscar and BAFTA-winning documentary, Free Solo.

Exhilarating, brilliant and dangerous, there is a purity to Alex's climbs that is easy to comprehend, but also impossible to fathom. In the last forty years, only a handful of climbers have pushed themselves as far, ‘free soloing’ to the absolute limit of human capabilities.

Half of them are dead.

From Yosemite's famous Half Dome to the terrifying heights of El Sendero Luminoso in Mexico, Alone on the Wall explores Alex's seven most extraordinary climbing achievements so far. These are tales to make your palms sweat and your feet curl with vertigo. Together, they get to the heart of how – and why – Alex does what he does.

Exciting, uplifting and truly awe-inspiring, Alone on the Wall presents an exploration of the world of extreme sports and the human ability to maintain a singular focus, even in the face of mortal danger.
