Radix: Radix Tetrad:

In a vastly changed world, thirteen centuries from now, Sumner Kagan searches the earth to find the godmind, a malicious being with reality-shaping powers. In this strange and beautiful world - eerily alien, yet hauntingly familiar - Kagan will change from an adolescent outcast to a warrior with god-like abilities and, in the process, take us on an epic and transcendent journey. Author's Note: The volumes of this series can each be read independently of the others. The feature that unifies them is their individual observations of science fiction's sub-genre: "space opera," which the editors David G. Hartwell and Kathryn Cramer define as "colorful, dramatic, large-scale science fiction adventure, competently and sometimes beautifully written, usually focused on a sympathetic, heroic central character and plot action, and usually set in the relatively distant future, and in space or on other worlds, characteristically optimistic in tone. It often deals with war, piracy, military virtues, and very large-scale action, large stakes."
