"Jack West Jnr is a marvellous character who is part Indiana Jones, part Robert Langdon and part Rambo."
A race against time and other coalitions sees Captain Jack West Jnr battle to save the world from a global catastrophe as predicted and safe guarded against by ancient civilisations. To do this six diamond bricks must be placed into the slots on six inverted bronze pyramids by a certain date - or planet Earth will be destroyed.
The six bricks are hidden around the world - as are the six pyramids. West and his team have to uncover the clues that lead them to the diamond bricks and the pyramids whilst battling hostile forces which comprise alternatively of Jack's father, a member of the British royal family, a Japanese professor and a Russian spymaster among others.
Allegiances shift back and forward as each group try to win the race to each pyramid as each places brick imbues a special ability into the person who places it into the pyramid. If anyone can save the earth then whoever does so will almost certainly inherit it.
The book starts where its predecessor Six Secret stones ended with Jack and his fathers opposing forces battling at the site of the second pyramid.
