This is a sequel to 'Touching The Void', in which Simpson described a fall in the Himalayas which crippled and almost broke him.

Joe Simpson has experienced a life filled with adventure but marred by death. In a narrative which takes the reader through extreme experiences from an avalanche in Bolivia, ice-climbing in the Alps and Colorado and paragliding in Spain before his final confrontation with the Eiger, Simpson reveals the inner truth of climbing.

Tackling the unclimbed west face of the remote Siula Grande in the Andes, Joe Simpson and his partner Simon Yates achieved the summit before disaster struck. A few days later, an exhausted Simon staggered into base camp to tell their non-climbing companion that Joe was dead. For three days he wrestled with guilt as they prepared to return home. Then a cry in the night took them out, where they found Joe, badly injured, crawling through the snowstorm. Far from causing Joe s death, Simon had saved his friend s life when he was forced into the appalling decision to cut the rope."

Is there a physics of society?

The book encourages us to examine our own behaviour, whether in buying the new Harry Potter book, voting for a particular party or responding to the lures of advertisers.
