Afternoon: An Introduction
Michael Joyce's Afternoon, a story was conceived for the Storyspace authoring system and published by Riverrun in 1989. It is currently available from Eastgate Systems. Afternoon has since established itself as a "classic" of the fledgling genre, earning kudos from the New York Review of Books and The Washington Post among others.
There are as many ways to interpret Joyce's text as there are ways to read it.
