The seven were previously strangers to one another so they spend their travelling time telling their stories in turn to the group in order to explain their interest in the Tombs, and the novel principally consists of these stories. Despite this, the seven proceed with their pilgrimage across an empty land, believing that they stand a chance of unravelling the mystery of the Tombs and the Shrike. The spaceport is besieged by the entire human population who are desperate to leave. When the seven arrive on Hyperion, they are greeted by chaos the Shrike has broken away from the constraints which had kept it close to the Time Tombs and is roaming the country, killing at will. They are also haunted by the deadly Shrike, a legendary being of only partly-glimpsed form consisting mainly of red multi-faceted eyes and steel blades, with the ability to appear and disappear at will. These mysterious, empty objects predate humanity and are surrounded by strange time eddies. The plot concerns seven very diverse people called by The Church of the Shrike to undertake a hazardous pilgrimage to the Time Tombs on the remote world of Hyperion. One of the avatars with a significant role is a recreation of the poet John Keats the author is clearly a fan.

Two other groups with a major influence on events are the Ousters, a renegade human group who had departed long before to live in space away from the rest of humanity and are now in conflict with the Hegemony, and the TechnoCore, consisting of human-created artificial intelligences which had thrown off human control and now had a parallel existence, mostly virtual but occasionally via human avatars. The setting is a 29th century human commonwealth known as the Hegemony, which spreads over a couple of hundred worlds in one sector of the galaxy. In fact, it's an unusual book with an unconventional structure and an inconclusive ending (just as well I have its sequel available, or I'd be feeling frustrated). It isn't quite what I expected, which was a conventional, if superior, space opera. However, I eventually stiffened my sinews, gritted my teeth and got stuck in. It is the size of a substantial doorstop so it sat on my shelf for a few months while I found excuses to read shorter books. I kept reading about how good the two Hyperion books were so I eventually bought an omnibus edition including both Hyperion and The Fall of Hyperion.
