Roderick Gordon and Brian Williams

In his quest to find his father, Will is plunged even deeper underground. As if things weren't bad enough already in the heat and darkness, he stumbles across a Styx plot with terrible implications for the world above.

Will Burrows and Chester find themselves in perilous circumstances after a long fall down the subterranean Pore. They land on a giant spongy fungus stuffed with artefacts from a lost golden age, but they are not alone!

Fourteen year old Will Burrows has little in common with his strange, dysfunctional family. The only bond he shares with his father is a passion for archaeological excavation. When his father mysteriously vanishes, Will feels he has to dig up the truth behind his disappearance.
