Project Gutenberg 2008-12-23 Public domain in the USA. 568 Clifton, Mark 1906 1963 Clifton, Mark Irvin 60009470 Eight Keys to Eden Produced by Greg Weeks, Geoffrey Kidd, Stephen Blundell and the Online Distributed Proofreading Team at https://www.pgdp.net "Eight Keys to Eden" by Mark Clifton is a science fiction novel written in the early 1960s. The story intricately weaves the experiences of several fictional characters, including a communications supervisor, a pilot, and a Junior Extrapolator, as they grapple with a critical situation concerning a delayed report from a colonization mission on the newly settled planet, Eden. The narrative revolves around themes of scientific inquiry, human nature, and the repercussions of failed communication in an isolated environment. The opening of the novel sets the stage for escalating tension as a communications operator realizes that Eden's scheduled report is overdue, alerting his supervisor and prompting a series of frantic measures to establish contact. As characters express skepticism about the colonists' accountability and the mysterious silence from the planet, a palpable sense of dread grows in E.H.Q. Furthermore, the narrative introduces a spectrum of characters—from the cynical supervisor to the determined pilot—each contributing to the unfolding drama surrounding the potential disaster. This introduction establishes an overarching mystery about the fate of the colonists, propelling the story into uncharted territories of both space and human behavior.
