This is the story of a strange and terrible world of the future. A world where children live without parents and family. There is no sense of the past in this world, no sense of history except in the mind of Lothar. Some say he is crazy; others only know that the Elders do not approve of his peculiar ways and that all conversations with him are forbidden. Dal is somehow attracted to Lothar, tolerating his impatience as he tells of past times that he has constructed in his mind from the scrapbooks he has hidden away in his cubicle.
