From Our Catalog:
The fall of Hyperion by Dan Simmons, 1990
Review from the Library Journal: While the worlds of the Hegemony fight a deperate war in space against the Ouster rebels who threaten galactic unity, a group of seven pilgrims on the planet Hyperion wage their own war within the Tombs of Time, a mysterious artifact which conceals a hideous creature whose freedom means death for humanity. In this sequel to Hyperion , Simmons weaves together many strands of a complex plot with lucidity and poetic imagination. Recommended.
