The author of Touching the Void interweaves stories of his own mountaineering adventures with reflective consideration of recent tragedies on the world's loftiest peaks. As more people take to the mountains--many of them amateurs and dilettantes who can afford to hire guides of varying levels of expertise--the odds of disaster loom ever higher. Simpson weighs in on "summit fever", the treatment of local sherpas, and what he sees as unimaginative yak routes up the once-grand mountains.
