Three kids arrive with their missionary father: Little Kevin loves exploring and is eager to open the locked door of the town's Great Wall. Middle-school aged Nicky is studious, well-read, masterful with computers and dying to control the town's computer and its friendly robots. Teen-aged Sandy is desperate for her father to succeed. It's his last chance with the old Galactic Missionary Society; his children have always stirred up just too much trouble. Sandy begins telling everyone about God, including the only other teen on the whole world. But the miners want their families left alone.
The kids find a secret, underground world of fuzzy, floating creatures calling themselves Foofs. Will Sandy teach them about God? The miners warn in tense whispers about ghosts from the underground. Is it all, as their father insists, just imagination?
A wild tale of humorous adventure, action and mystery. Come enjoy the new world of Christian science fiction that's fun for the family.
