A Venusian Odyssey! To its people, Venus is a bright hemisphere in an unending ocean of cold darkness. To Hunter, it is the Land of Never Change, its civilization as static as its eternally light gray sky. He outfits an expedition to give his people new knowledge of their world, and makes some shocking discoveries. Venus is a sphere, with a light side and a dark side. And above the sky are points of light, one a brilliant blue-white. Hunter refits his ship to withstand the vacuum, and sets out to explore Venus's neighbor in space. It's an odd world, its blue skies and blinding orb giving way to darkness, and vice versa. A troubled world, convulsed in global war. A world called Earth.
