Atherton

This riveting adventure is set in a satellite world created as a refuge from a dying Earth. Edgar, a gifted climber, is a lonely boy scaling the perilous cliffs that separate the three realms of Atherton, including a vast wasteland where he must confront an unspeakable danger that could destroy his people. When Edgar discovers a book containing the history of Atherton's origins and ultimate apocalypse, his world quite literally begins to turn inside out.

After journeying to an unfamiliar land where air is nearly unbreathable and light stings like shards of glass, Edgar must navigate the deadly forests--full of creatures far more frightening than anything he has seen on Atherton--and join the child workforce of Silo #7, the site where Dr. Harding (the mad maker of Atherton) was raised.
