 Humanity has colonized the solar system and moved outward to begin exploring the far reaches of the galaxy. An interplanetary audience follows real-life stories of triumph and tragedy presented to them by Duncan Chalk, a media mogul with apparently limitless resources. Chalk, unknown to all around him, is a kind of psychic vampire who draws sustenance from the emotions of others, particularly those of pain and trauma. Though he enjoys playing his inner circle of assistants against each other as a sort of daily snack, Chalk's true nourishment comes from the dramas he orchestrates for his audience. Chalk's latest drama involves the pairing of Minner Burris, a space explorer who was captured and surgically altered by aliens on the planet Manipool, and Lona Kelvin, a 17-year-old girl who donated eggs for a fertility experiment that produced a hundred babies. Burris, whose freakish appearance draws attention whenever he ventures out in public, has withdrawn into seclusion and bitterness. Kelvin, whose brief fame as the virgin mother of an army of children has begun to fade, has twice attempted suicide because she has not been allowed to adopt or even see any of her offspring. Chalk promises Burris a full round of surgery and treatment to restore his human appearance, and offers Kelvin a chance to adopt one of her babies, if the two agree to come together for an all-expenses paid tour of the solar system. At first the two wounded subjects enjoy each other's company and even become lovers. Kelvin's empathy and compassion are stirred by Burris's plight, and Burris enjoys playing masculine protector and guide to the naive teenager. The affection soon curdles into irritation, hostility and even hatred—all of which provide a psychic feast for Chalk. The two finally break off after a particularly vicious fight, which Chalk uses as a pretext to void the agreement. He does, however, try to keep them on the hook by dangling new offers: for example, he asks Kelvin to befriend David Melangio, a childlike man whose feats of memory and calculation are his only means of meeting a world that has already subjected him to overwhelming traumas. Kelvin erupts in rage and is carried off by Chalk's assistants. Burris, meanwhile, has a sexual fling with Elise, the widow of an astronaut who accompanied Burris on the Manipool landing, and who died from the surgical alterations performed by the aliens. Elise is both aroused and repulsed by Burris' body, and the sadomasochistic nature of her attraction eventually alienates Burris. His withdrawal causes her to commit suicide in a particularly grisly fashion. Burris, deeply shaken, returns to Earth. He has realized that Chalk's promise was empty, and that such help may no longer even be possible—the changes wrought by the Manipool aliens appear irreversible. What's more, the surgery that turned him into a monster has also "improved" his body in unexpected ways that Burris has come to appreciate. With the inadvertent help of Melangio, who during a typically bland chat lets slip some information that gives them clues into Chalk's true nature, Kelvin and Burris confront the media baron in his office. They expose the full, unfiltered core of their mutual pain to Chalk, who is overwhelmed and finally killed by the intensity of the emotional flood. As the novel ends, Burris has convinced Kelvin to join him in a trip back to Manipool, where they will confront the aliens and, presumably, undergo alterations that take them beyond humanity.
