Fall of Hyperion -- Dan Simmons
Taking place mere moments after the events of Hyperion, this novel is framed from the perspective of a cyborg of the poet John Keats whose origin and purpose remains obscure—even to himself. Keats reflects on the acedia of a civilization, dependent on omniscient AI, spoiled with instantaneous interplanetary travel, as it spirals out into a calculated interplanetary war. Wrapping up the narratives of the travelers from the first novel as they confront the Shrike monster, Fall of Hyperion raises large and ambitious questions.
