The Shadow of Heaven
Description from the back of the book
Those who tried never returned....and those who didn't always wondered what they were missing by not attempting the perilous journey to 'Heaven'...
The official designation fo the giant anti-gravity floating disc was 'International Land Extension U.S.23' But to the people living like sardines in the fam-apts and dormitories on the ground below, it was known as 'Heaven'.
Government regulations meant that it was almost impossible for a human being to get to 'Heaven' - almost, but not quite, as Vic Sterling found out when he began to hunt for his missing half-broher Johnny Considine. For Johnny, along with over a hundred other rebels, had decided they could no longer stand the living conditions on Earth and had hitched a ride to 'Heaven'....a 'Heaven' full of unexpected dangers for Vic when he decided to follow.
Condition - Good, signs of wear both on the cover and the spine. At one point the book has been squashed but the pages are still tightly bound. Pages have begun to yellow.
