To Reign in Hell: The Exile of Khan Noonien Singh
Greg Cox
 The book begins with Khan, Lt. Marla McGivers, and most of the other supermen and women that had been with him on the SS Botany Bay arriving on the planet Ceti Alpha V. Khan is given supplies and a phaser and begins to build a colony on the planet. Khan is challenged several times by his fellow supermen, but remains in control for the most part. Some time after arriving, the next planet in the Ceti Alpha system, Ceti Alpha VI, explodes and disrupts the orbit of Ceti Alpha V. This causes major climate changes and loss of plant and animal life. Khan and the supermen take refuge underground and Khan waits for Kirk to arrive and rescue him and his followers from the hell that has become of the planet. After more time passes, several supermen do not wish to follow Khan any longer and try to assassinate Khan by placing a Ceti Eel in Marla McGivers' ear. This bizarre creature causes her to do whatever is commanded of her, and the men order her to kill Khan. Marla's love for Khan allows her to resist enough to instead kill herself. The eel emerges from her ear after her death and Khan sees the reason why she died. After the failed assassination, the rebels leave the underground and form a new faction on the planet, taking control of the vital hot springs that provide the only water on the planet. Khan then battles them, losing many men and women, but winning in the end. At the end of the novel a few years later, Khan sees two men in space suits materialize on the planet's surface. Throughout the novel, Khan blames his hardships on James Kirk for stranding him on the planet and never checking on him again.
