Publisher's Summary

This riveting adventure is set in an extraordinary satellite world created as a refuge from a dying Earth. As the satellite begins to collapse, the lives of its inhabitants are forever changed. Edgar, a gifted climber, is a lonely boy scaling the perilous cliffs that separate the three realms of Atherton: a humble fig grove; a mysterious highland world of untold beauty and sinister secrets; and 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.
