"It was said Treemoonia had a memory that helped to keep important things important . . . "
In the trees of Treemoonia, the people are content, work hard, and help each other. If they follow the Parabole, the book that tells of how they began, then their land is blessed. But not everyone believes in the Parabole or the Winds of Treemoonia, and they must deal with the consequences of their unbelief deep beneath the sheltering trees of their homeland.
Tommy is just another Treemoonian child, enjoying a siesta day with his friends, with his sister underfoot. Annoyed that she insists on following him, Tommy does his best to lose her-that is, until he actually loses her for real.
As Tommy frantically tries to find his sister, he stumbles across a stepping vine leading beneath Treemoonia. Knowing his sister may have followed the same vine, Tommy soon finds himself going deep down into a dark world, where creatures are not what they appear and where his questions are met with hatred and fear.
Will Tommy be able to find his way back home with his sister safely in-hand? Or will the creatures beneath Treemoonia swallow him up for good and keep him captive in his disbelief? The answers can be found only in the Parabole-if only Tommy will believe what he already knows.
