On the planet Hyperion, beyond the reach of galactic law, waits a creature called the Shrike. There are those who worship it. There are those who fear it. And there are those who have vowed to destroy it. On the eve of Armageddon, with the known universe at war, seven pilgrims set forth on a final voyage to Hyperion seeking the answers to the unsolved riddles of existence. As the Shrike anticipates their mission, each traveler nurtures a desperate hope—and harbors a terrible secret. And one may hold the fate of humanity in his or her hands.
