There is no FTL technology, so people travel in "lighthuggers" starships that travel at just below the speed of light on decades-long circuits of habitable worlds. Humanity has settled the stars, but encountered no sentient alien life. Revelation Space takes place in the 25th century. However, it is an earlier novel, and it shows, as I found that I enjoyed Revelation Space somewhat less than House of Suns. House of Suns was a story told with a sweeping scope on which the fate of galaxies literally hinged, and Revelation Space is nearly as ambitious. Reynolds writes large-scale sci-fi, with million-year-old civilizations, post-humans who are genetically and cybernetically modified sometimes to the point of barely being human, and slower-than-light travel in kilometers-long starships. The universe and characters are very similar to the first Reynolds novel I read, House of Suns. It's the first in the Revelation Space series, but it's a stand-alone novel. This is my second Alastair Reynolds novel.

And if that reason is uncovered, the universe - and reality itself - could be irrevocably altered. But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason. With no other resources at his disposal, Sylveste forges a dangerous alliance with the cyborg crew of the starship Nostalgia for Infinity. Now one scientist, Dan Sylveste, will stop at nothing to solve the Amarantin riddle before ancient history repeats itself.

Nine hundred thousand years ago, something annihilated the Amarantin civilization just as it was on the verge of discovering space flight.
