Empire Star is a 1966 science fiction novella by Samuel R. Delany. It is often published together with another book, most frequently (three times) with The Ballad of Beta-2. Delany hoped to have it first published as part of an Ace Double with Babel-17, but instead it was published with Tree Lord of Imeten by Tom Purdom. It was finally bundled with Babel-17 in a 2001 reprint.The story revolves around the protagonist, Comet Jo, and a narrator named Jewel. Nominally a tale of Comet Jo’s coming-of-age, his education into galactic society (and as such can be considered a mini-Bildungsroman), his efforts to deliver an important message to Empire Star, and the attempt to bring an end to slavery, the story has several layered loops of events which run back upon themselves—and the concepts, layering, and ordering of the events are as important as the story itself.
