A Canvas of Rock transports the reader through two of the most influential periods in modern British rock-climbing as seen through the eyes one of the UK's well-respected rock climbers - Mark Radtke. This collection of personal experiences and friendships with climbers from the 1970s to the present day, provides a rare insight and first-hand account on some of the crucial and at times contentious episodes that paved the way to today's rock-climbing scene. We are also treated to insights of the man himself - his passion and his drive that have allowed him to challenge his limits and to pioneer many new Extreme routes. 'Rad shows us his own frailties - his vertigo, his occasional bursts of egocentricity - and this makes him a convincing guide. It is a great read, full of humour and drama, but at the same time it is a wise and important contribution to the ongoing debate of climbing ethics. Where slipping into the comfort zone does not and must not equal progress.' From Foreword by Andy Cave
