Earth is dying. Its human population has declined catastrophically; people have become so isolated that few children are being born. The usual cause of death is self-termination.The Futurists, aided by the worldwide Computer network known as Central, take a desperate gamble. They reach into the past to extract candidates who might possess the qualities that the people of 25th Century Earth have lost; courage, determination, curiosity, stubbornness. But how to know if they've found the right ones?The candidates are transplanted to a parallel Earth during the late ice age; a world of giant mammals; bison, mammoths, dire wolves, sabertooth cats. Equipped with only a knife and hatchet, they must survive or perish on their own. Their children will in turn be transplanted to future Earth to revive its failing civilization.But first, they must survive this survival-of-the-fittest world...Fans of Robert A. Heinlein and S. M. Stirling will love this book's imagination and attention to detail!
