Finn thinks he has trouble enough, hanging out alone on the streets of Kings Cross, until he stumbles on sinister figures pumping vile-smelling sludge into the drains. Then his life starts to get seriously weird.
Who - or what - are these Tankermen? How can they disappear into solid rock?
What Finn faces when he follows the Tankermen into their hideout is horrifying beyond his worst fears.
This is a gripping fantasy adventure, written with style and assurance by the author of WildGame and Walking through Albert.
