The Solanders adventure continues with... COMPUTATION OF THE UNKNOWN After thwarting a Centaurian attack on Soland and becoming a prisoner of Centauri, Lora Callisto struggles to adapt to life in a labor camp on the Centaurian home planet of Zanth. In Soland, Tanel and Arek, whose lives were wrenched upside down by Lora's jarring departure, are driven by the heartache of not knowing her fate to devise a bold plan to search for her. Meanwhile, after years of computation, XC, the vast-minded automation system running all of Soland, finally arrives at its own conclusion as to the best solution to the human tendency toward conflict. When a risky opportunity arises for Lora to get out of the labor camp, she decides to chance it, leading her to unexpected encounters and a new mission she never imagined she would be part of--the outcome of which will determine the future of all of humanity.
