The Einstein Intersection

The Einstein Intersection won the Nebula Award for best science fiction novel of 1967. The surface story tells of the problems a member of an alien race, Lo Lobey, has assimilating the mythology of earth, where his kind have settled among the leftover artifacts of humanity. The deeper tale concerns, however, the way those who are "different" must deal with the dominant cultural ideology. The tale follows Lobey's mythic quest for his lost love, Friza. In luminous and hallucinated language, it explores what new myths might emerge from the detritus of the human world as those who are "different" try to seize history and the day.
