'Riccardo Cassin has written a masterpiece of an autobiography—possibly the most important mountaineering book to be published in the last twenty-five years! It's all here—a scintillating record of a half century of high-standard Alpine endeavor: his first climbs in the Grigna, the Dolomites, the north face of the Cima Ovest, the north face of the Piz Badile, the Walker Spur of the Grandes Jorasses, the Cassin Ridge of McKinley, Jirishanca, Gasherbrum IV and Lhotse. Perhaps the world's best climbs done by one its best climbers. What more could one ask for?”
