The Hyperion Cantos is a series of science fiction novels by Dan Simmons.
The story weaves the interlocking tales of a diverse group of travelers sent on a pilgrimage to the Time Tombs on Hyperion. The travelers have been sent by the Church of the Final Atonement, alternately known as the Shrike Church, and the Hegemony (the government of the human star systems) to make a request of the Shrike. As they progress in their journey, each of the pilgrims tells their tale.
