Book Four of the acclaimed Radix Tetrad.
Seven billion years from now, long after the Sun has died and human life itself has become extinct, alien beings reincarnate humanity from our fossilized DNA drifting as debris in the void of deep space. We are reborn to serve as bait in a battle to the death between the Rimstalker, humankind's reanimator, and the zotl, horrific creatures who feed vampire-like on the suffering of intelligent lifeforms.
The reborn children of Earth are told: "You owe no debt to the being that roused you to this second life. Neither must you expect it to guide you or benefit you in any way." Yet humans choose sides, as humans will, participating in the titanic struggle between Rimstalker and zotl in ways strange and momentous.
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."
