Alex Honnold is 28 years old, and perhaps the world's best 'free solo' climber. When Alex performs one of his long free solos, the severity of which no one else has yet dared to attempt, he does so without a partner and without equipment, including rope. Alone on the Wall is structured around Alex's seven most extraordinary climbing achievements so far. These are tales to make your palms sweat and your feet curl with vertigo, told by a smart, likeable climbing visionary who, as Jon Krakauer says, is 'utterly genuine. There's no bullshit there.'
