A ghost ship carries a deadly alien spore... Out of the black, a ghost ship on a collision course hurtles towards Alexandria, threatening to destroy the colony. A salvage team races to intercept the massive interstellar ship, but once on board they find...nothing? No survivors, no remains, only the desiccated corpse of an alien horror. Shaken, they return home, unwittingly carrying the horror with them. Infestation fills every nook, every cranny. The command staff of Alexandria races against proliferating monsters threatening their domed haven. The colony fights back, struggling to understand what's killing them, while Elke and the rest of Eden watch the massacre unfold from afar, unable to help.
