'Fox and Amy think they are in control of their Australian bush environment and play deadly games on city visitors. Jacques, older but 'weird', entices them to help him explore and map underground caves and they enter a beautiful, dangerously unknown environment.
'When City Boy lies injured and Jacques becomes irrational, Amy and Fox must find the way out; escape from the maze of caverns where foul air wanders and the twinkling flowstone beckons. And exciting, realistic, sometimes sinister adventure.'
