Earth is dying. 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.
This is their story.
