After DEEPER, can the TUNNELS adventure get any more dangerous? And where will it end?
Will Burrows and his gang are far from finished as they free-fall down a subterranean pore. As they experience reduced gravity, the dark mysteries of the deep unfold and they discover a strange fungal shelf, which not only reveals artefacts from ancient civilisations, but clues to a lost land at the end of the Earth.
