In the year 2239, when the human race faces extinction, the last salvation of the species is on a colonizing mission to Alpha Centauri. But a terrorist plague has infiltrated the ship. A miraculous relic of an earlier doomed race awaits them--a puzzling and impossibly ancient artifact that offers hope beyond mortal comprehension or stands as a grim harbinger of the impending death of everything human.
