"Bucholz (Severance) has deftly constructed a believable future that explores the environmental and social effects of a radical solution to global warming. The breakdown of governmental order and personal relationships, and the attitudes toward disabled people who are viewed as unable to contribute to either, form a frightening portrait of the tendencies of communities to isolate in times of devastation."

Synopsis:
The Earth is icing over and no one knows how to shut the Shade off. Every attempt in the last thirty years has failed and humanity is nearly out of options if they want to regain a world that isn't covered in snow and ice. Gabe Alfil may be the only person alive with enough expertise in quantum computing to solve the problem, but a hiking accident a decade earlier has left him paralyzed, and the key to saving the world requires a dangerous trek across a frozen wasteland.

Between chases across the icy landscape, kidnapping attempts, and computer hijacking, Gabe quickly realizes that not everyone wants to save the world.
