The Einstein Intersection - Earth has lost its humans, and their corporeal form has been taken over by a race of aliens who, in an attempt to make coherent sense of the human artifacts among which they live, take on human traditions, too. The trek of Lobey, an alien Orpheus, leads him to the Dove, fabulous love image of a world obsessed; Greeneye, victim of a dead race's millenia old ritual; and Friza, the dark and silent girl he searched for to the shores of death- and beyond...

The Einstein Intersection won the Nebula award for "best novel" in 1967, and was a Hugo-nominee in 1968.
