Empire Star
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. Plot summary. As the narrative opens, we meet Comet Jo at eighteen years of age. He has spent his entire life in a "simplex" society on Rhys, a satellite of a Jovian planet orbiting Tau Ceti. (At first it might seem that "simplex" means "simple" or  unintelligent, but after Jo's encounter with the "Geodesic Survey Station" at the latest, it will be clear the notion is much more complicated.) Jo comes upon the wreckage of a spacecraft and encounters two survivors. The first is quickly dying and asks Jo to bring an important message to Empire Star moments before passing away. The other is a lifeform known as Jewel. Jewel is a tritovian in crystallized form, and in that state can easily view situations from several points of view, thus enabling narration from the point of view of the omniscient observer. Jo quickly leaves Rhys  in an attempt to deliver the message to Empire Star, and on his journey he meets several other characters along with a race of creatures known as the Lll. The Lll are incredible builders—not merely of structures, but of ecosystems, societies, and ethical systems. As such, they have been enslaved. However, in order to protect the Lll, the Empire has created a phenomenon known as “the sadness of the Lll”—any being who owns the Lll suffers from a constant, overpowering sadness. This sadness increases geometrically with each Lll owned and with how much each Lll builds, so it is  only possible to own a few Lll at a time. Indeed, just being in the presence of the Lll is a heartbreaking experience for even non-owners, a lesson that Jo learns early in his travels. The story then follows Jo over the next few months. Once he reaches a certain point in his maturity, knowledge, and ability to perceive events around him, the linear narrative stops and the reader is left with a few pages of important events not arranged in a strict order; by this point, the reader may have learned enough to sort out the tangle. Along  the way, several questions are raised, either explicitly or implicitly. What is the message that Comet Jo must deliver? Who is coming to free the Lll? Will the Lll ever actually be freed? Is the story a closed loop, or is there indeed an end (or at least a point at which events move on past the ones mentioned in the story)? Who, exactly, entered the Empire Star? How many of the events of the story are arranged by those people?
