After DEEPER, can the TUNNELS adventure be 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 artifacs
from ancient civilisations, but clues to a lost land at the end of
the Earth. The third in the thrilling Tunnels series - an
inernational publishing sensation.
