At the frozen bottom of the world, a madman sits. Supposedly a weather monitoring installation, TESLA can actually control the weather...and Greg Simpson, TESLA's designer, isn't about to give up that control to anyone. Not the international agribusiness corporation that bankrolled TESLA; not the US military, who have made a secret pact with Simpson to turn weather into a weapon; and certainly not Tess Beauchamp, an upstart weather scientist who had the nerve to disobey Simpson ten years earlier.
Simpson's removal triggers planetary cataclysms: massive storms, earthquakes, and tsunamis are just the tip of the iceberg. Unless Tess and the equally brilliant Nik Forde can crack TESLA's programming, Mother Nature's fury will quickly turn the Earth into a lifeless husk.
