The Science Fiction genre is rich with retelling of fairy tales. Sometimes these ret el lings are deliberate, sometimes they seem to be almost accidental, and sometimes they are inspired by the fairy tale but do not stay strictly within its structure. The Snow Queen by Joan D. Vinge is an example of the third type, in which the Anderson fairy tale provides that backbone for a much larger story. This tale, which won a Hugo award, is one of the best clone stories ever written. But it's much more–a tale of cultural upheaval, a confrontation between good and evil, and a deeply moving love story. In the song, Moon Dawntreader Summer is telling about her duty as a sibyl and her need to go home and rescue her people.
