Deep under Britain is a secret country called Inferus, whose strange peoples - the Gigans, Auctors and Minutis - have evolved a technologically advanced civilization both like and unlike our own. Cars, phones and lifts are common, but crime and violence are not. Until, that is, a group of revolutionaries plot to destroy Inferus unless they are allowed to leave for the "Overworld". In a desperate bid to save their country and its way of life, the inferusian government turns to three human children and their dog - their mission: to hunt down the criminal mastermind behind the plot. Time though, is running out...Witty, fast paced and wonderfully imagined, this children's thriller should appeal to boys and girls between 9-12 years old.
