Between 1925 and his death in 1940, Emilio Comici was the pre-eminent climber in the Eastern Alps, the hotbed of global rock climbing at that time. He made first ascents on some of the highest and most notorious walls in the Alps, including the northwest face of the Civetta, as well as dozens of other climbs.

Comici invented many modern big-wall techniques and the big-wall idiom itself that later took root in Yosemite Valley. Comici also made solo ascents of some of the hardest routes in the Alps, including his climb on the north face of the Cima Grande. He also designed the first artificial climbing wall that was ever actually built.

This book explores how family tragedy and growing up in working class Trieste under Austrian occupation shaped Comici's complex personality and attitudes toward climbing. He was loyal to his friends, deeply concerned about the vulnerable, including his fellow climbers, and yet highly competitive, a born vagabond and yet also a dandy, irresistible to women, and yet unable to settle down, devoted to his mother and to the mountains, and finally, like many other Italian climbers of the period, a member of the Italian fascist party although he was profoundly anti-German and opposed to racial persecution.
