Neal Stephenson's sweeping, prescient novel transports readers to a near-future world where the greenhouse effect has inexorably resulted in a whirling-dervish troposphere of superstorms, rising sea levels, global flooding, merciless heat waves, and virulent, deadly pandemics. One man has a Big Idea for reversing global warming, a master plan perhaps best described as "elemental." But will it work? An exhilarating, witty, mind-expanding speculative adventure.
