Around the world entire towns are being wiped out, a trail of boneless bodies left behind.

Professor Matt Kearns, paleo-linguist, and a team of scientific and military specialists, rush to decipher the hidden secrets of a pair of ancient stones that prophesize the next great extinction on Earth. They soon discover that the ominous predictions are linked to a plague of unstoppable creatures that have risen from the centre of the Earth.

In a heart-pumping adventure that begins in the hold of a sunken German U-boat, Matt Kearns travels to the lost Nazi treasure tunnels in Poland and dives deep down to sunken caves below Easter Island.
