Kuldesak

Earth, two thousand years after the final holocaust which drove man deep underground; a ghostly, deserted landscape peopled only by the diligent robots who, century after century, silently harvest grain which no man will eat.
Up into this eerie world comes Mel, a questioning young Roamer who has disobeyed the Law which says he must never venture into or beyond the Lost Levels. Together with three companions, and a companion not of this Earth, Mel takes on the awesome task of freeing human beings from the tyranny imposed on them by their remote ancestors; of justifying the agonized cry on Barney as he died in a forbidden level: 'I am a man! Everything is for man!'
Kuldesak is a gripping, brilliantly inventive new novel by the author of Phoenix and Breakthrough.
