An epic collection of science fiction and cosmic horror stories by George R. R. Martin, Nightflyers follows nine misfit academics on a deep-space voyage to the edge of the known universe in search of first contact with a mysterious alien species. Aboard the Nightflyer, a seemingly sentient spacecraft commanded by an unseen captain, the crew soon realises that the greatest threat may not lie outside the ship, but within it. As paranoia and terror take hold, they face a deadly force stalking them from within the vessel itself. The collection also includes five additional stories exploring the limits of technology and the darker depths of the human mind.
