Danny MacAskill lives on the edge.

The cyclist is legendary for his YouTube viral videos like The Ridge, Cascadia, Imaginate and Wee Day Out: nerve-racking montages of stunts which scale everything from mountain peaks, rooftops, ghost towns and movie sets. His life is one of thrills, bloody spills and millions of online hits.

It hasn't been an easy ride. Doubt, stress and the 'what if?' factor circle every trailblazing trick, which require imagination, fearlessness, groundbreaking techniques and an eye for a good camera angle. 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 the next level - both mentally and physically.

Join Danny for a nerve-shredding ride. Just be sure to bring a crash helmet.
