Dark Eden is the first of Chris Beckett's trilogy set on the sunless world of Eden, located across the galaxy and reachable only by a physics-defying starship that took a generation to build. While many characters are introduced, the novel centres on John Redlantern, a restless young man who chooses to leave the Circle to seek new sources of food, defying the wisdom of the elders who insist on living within reach of the landing site so that they can be found when rescue comes.
The novel explores the way that historical events can grow into mythology or religion, as well as the inevitable battles between change and the status quo, and the difficulty in keeping to a well-intentioned moral system. In the process two worlds are created in deep convincing detail - the alien ecosystem of Eden, with bioluminous lifeforms all dependent on the "trees" that constantly pump up heat from the core of the planet; and the society of the humans with their Earth beliefs, their simple morals, child-like language and genetics - due to the small and incestuous gene-pool, genetic defects such as "batfaces" (cleft palate) and "clawfeet" recur in each generation. The title is apt - this is truly a dark vision of a desperate society.
