In the last book of the Revelation Space trilogy, humanity is in disarray as the Inhibitors ravage space. But there is a glimmer of hope, a young child named Aura seems to have a connection with entities that can help. As the story unfolds on the refugee world of Ararat, and the religious pilgrimage destination Moon of Hela, tired remnants of humanity must make fateful decisions about how to approach the resources presented to them. Who can be trusted?
This is a long and sprawling book, and it feels rather ponderous. Mr. Reynolds’s prose is as engaging as ever, but many digressions, tangents, and diversions are overlong. The obsession with Scorpio’s mortality, the machinations of the Quaicheist church, the extensive details on the madness of Quaiche himself, to name a few things, are explored somewhat excessively at the expense of moving the story forward. For much of the novel, it feels as if nothing is really moving, or perhaps things are moving as slowly as one of the cathedrals on Hela. The Inhibitors themselves seem like a distant threat, so it is hard to work up a real sense of dread for them, even if the survival of humanity itself is at stake. As a conclusion to the trilogy, it is somewhat unsatisfying, even if the personal journeys of the characters come to a conclusion.
