Here is the Prometheus Blog Appreciation of Donald Kingsbury’s Courtship Rite, the 2016 Prometheus Hall of Fame winner for Best Classic Fiction.
As an opening epigraph in Glory Road, Robert Heinlein quotes some lines by Bernard Shaw that include the sentence “He is a barbarian, and thinks the customs of his tribe and island are the laws of nature.” One of the things science fiction can do for its readers is to jar us out of such complacency, by portraying worlds with customs other than ours – not utopias or dystopias, but heterotopias, “other places.” Donald M. Kingsbury’s Courtship Rite is one of the great heterotopias.
