F our astronauts return to Earth after a three-year absence while on the first manned expedition to Mars. But the home they left behind no longer exists.
A lethal pandemic has obliterated eighty percent of the population and decimated the social and physical infrastructure of civilization. Pandemic survivors, their minds altered by post-traumatic stress disorder, have learned to be wary of strangers. Many survive only by ignoring all ethical codes and applying skills appropriate for their cave-man ancestors.
How do these former astronauts find meaningful existence in a chaotic anti-society so alien to them? Only by redefining their lives, questioning their values, and learning new survival skills can they adapt to this world in transition.
