Books like The Other End of Time

A distinguished veteran of science fiction, Frederik Pohl was one of the Futurians, a New York City club of the 1930s and '40s that included Isaac Asimov. Author of The World at the End of Time, his latest novel features Dan Dannerman, a poorly paid government agent in the not-too-distant future. Dannerman discovers aliens on an abandoned space station and is drawn into a conflict that encompasses the universe. According to one of its protagonists, the war Dannerman blunders into centers on what "ordinary people have been used to calling 'Heaven.'" A sequel is promised.
