Kelly Cordes turns a tough mountaineering objective into a collision of wills, personalities and visions for the sport in this new book. From the 1959 claim of a first ascent to subsequent attempts to verify the accomplishment, Cordes lets events unfold without contrived conflict or undue emotionalism. Capped by the recent chopping of bolts on the Compressor Route, there’s enough to keep readers on edges and ledges in this self-propelled read.
