In fact the first three sections of the novel—through Killashandra's return from her first experience cutting crystal in the field—are moderately revised and heavily revised versions of the first and third 1974 stories, "Prelude to a Crystal Song" and "Milekey Mountain". In the second and fourth original stories she is a veteran of more than 100 years in the field. Whether and how she may be able to go on as a woman on vacation (#2) and as the miner of her claim (#4) are primary themes.
