Synopsis: From the back cover of the Ace Books first edition: There it was - the world of the Overshoot. Greenhouse Earth, the greatest catastrophe in the history of civilization, which had crept up on us unaware like a thief in the night... Eighty-year old Moira Burke had expected life to end with nuclear war - simply and quickly. But like a cruel prank, the real threat had become global warming - a much slower destruction. By 2032, a rise of five degrees Fahrenheit meant human life had become dictated by natural disasters. Chaos loomed, it approach marked by raging floods and extreme heat. Mother Nature had survived a meteor millions of years ago - and She would survive us. But would we survive...? What Moira doesn't yet realize is that survival will not depend on the evolutionary course of time. In fact, it will depend on our own genetic creation - a bold new experiment called "The Green Man". A bold new chance for life and a magnified glimmer of hope...
