Jem

The discovery of another habitable world might spell salvation to the three (Food Bloc, Fuel Bloc & People Bloc) bitterly competing power blocs of the war torn & resource-starved 21st century. But when their representatives arrive on Jem, with its three intelligent species, they discover instead the perfect situation into which to export their rivalries. Subtitled, with savage irony, 'The Making of a Utopia', Jem is one of Frederik Pohl's most powerful novels.
