Book Three of the acclaimed Radix Tetrad.
Earth's last hope
The Arc, a being of immense power, trapped within a continuum too small, fights for its freedom. Its monumental struggle will touch a few select individuals on Earth - and in doing so, change their lives forever. The Arc may also be the last hope for humanity's survival.
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."
