Danny MacAskill lives at the edge. The cyclist is legendary for his YouTube viral videos like The Ridge: nerve-jangling blurs of stunts and speed over towering buildings and mountain peaks. His life is one of thrills, bloody spills and millions of online hits. It hasn't been an easy ride. Fear, stress and the 'What if?' factor circle every trailblazing trick, all of which require imagination, daredevil techniques and movie-making smarts. He has spent his life pushing the extremes - somehow, he's still around to tell the tale. In this unflinching memoir of mayhem, Danny shares his anarchic childhood on the Isle of Skye and early days as a street trials rider, takes us behind the scenes of his training and videos, and reveals what it takes to go beyond the next level - both mentally and physically.
