InspirationBelow the Root is adapted from the original 1978 'science fiction fantasy' novel written by Zilpha Keatley Snyder, and is the first in Green-Sky Trilogy, Followed by the books: And All Between (1979) and Until the Celebration (1980).
The game was a direct result of readers' dissatisfaction with the ending of the books. Agreeing with a lot of the criticism, author Zilpha Keatley Snyder decided that a computer game might be used to continue the story and provide a better resolution to the series' events. Much of the game focuses on discovering the hidden truths behind some of the events described in the final novel.
