With a bad attitude and destructive ways, ten-year-old Troy Finnegan is offered a chance to visit God's four hidden
civilizations. There he and his seven-year-old sister, Elizabeth, are magically transformed into tiny people and transported from one hidden world to another by their ever changing guide, Zeke. Zeke, who is a Tree Traveler, takes them on this guided tour by transforming himself into different creatures along the way. Once there Troy tries to make right the wrongs he brought upon these worlds.

While in each of the four hidden worlds, Troy and Elizabeth meet some of the oddest and most lovable creatures imaginable. They include:
• The dirty yet lovable Denizens of the Dirt, underground dwellers with a habit of borrowing.
• The aquatic Gillmen, half fish-half human, full of questions and a curious nature.
• The festive Tree Travelers, full of merriment and the enjoyment of life.
• The Clan of the Clouds, a society filled with the beauty and splendor of God’s rainbow.
