For Jack West and his team, unlocking the secrets of the `Seven Ancient Wonders' has proved only the beginning. The world is still in mortal danger.
The challenge now is to set six legendary diamonds known as the `Pillars' in their appointed places before the deadline when global destruction is predicted. But first Jack and his team must locate the exact positions of placement all around the world, at sites known as `the Six Sacred Stones'.
What follows is a terrifying chase on a mountaintop railway in remotest China . . . A midnight expedition to unlock the prehistoric secrets of Stonehenge . . . Belly-crawling through subterranean tunnels infested with giant Nile crocodiles . . . Surviving the gruesome rituals of a cannibal tribe in forgotten jungle valleys of the Congo . . . A race-against-time submarine journey to an abandoned city hidden under the Cape of Good Hope . . .
With only the riddles of ancient philosophers to guide them, they must find their way through complex networks of traps and labyrinths and ambushes - and all the while warding off hostile interference from some very powerful and determined enemies.
