What bizarre changes have overtaken the human colonists of the planet Aeran? They have forgotten their origins and their society has reverted to that of a Stone Age culture that flourished on Earth centuries ago. Is it a racial memory that has been awakened? Or is there a more alien reason for the change, embodied in the symbol of their oracle, the Earthwind? Elspeth Mueller and Peter Ashka have both come to the planet to seek the truth behind the Earthwind - but they have brought with them the seeds of their own slow destruction. Their quest is a race against time; for it is Time that holds the key to the mystery and Time will soon destroy them...Cover art by Michael Posen.
