Revelation Space is a science fiction book by author Alastair Reynolds.

The dig that begins the novel unearths something very disturbing for scientist Dan Sylveste. A patrician son of the wealthy, Sylveste does not welcome any interruption in his quest to find out what happened to the previous inhabitants of the planet Resurgam. They were extinguished en masse, just as they were on the verge of achieving interstellar space flight. It appears that this might not be purely accidental. He requires the assistance of the crew of Nostalgia for Infinity, a huge gothic spaceship cathedral with a cache of "hell class" weapons. But there's a tiny problem with the Captain. And Ana Khouri, a recent addition to the crew, has an ulterior motive for joining.
