The Seed Garden — D.B. Reynolds-Moreton

The prospect looked grim for Jed; alone, his escape pod crashed on an uncharted planet with no hope of rescue. But after he died a painful grizzly death in the dry desert things began to look up.
The lifeless planet that Jed now roams turns out to hold a secret vital to the existence of life itself.

David Reynolds-Moreton takes us on a journey of discovery through strange and hostile landscapes, and into the depths of a machine so staggeringly vast and at the same time utterly believable. Whether you see the twist at the end coming or not, you'll be completely drawn in.
