Archaeologist Jack Howard is a brave but cautious man. When he embarked on a new search for buried treasure in the Med, he knew it was a long shot. When he uncovered a golden disc that spoke of a lost civilization more advanced than any in the ancient world, he started to get excited.

Marine archaeologist Jack Howard has stumbled upon the keys to an ancient puzzle. With a crack team of scientific experts and ex-Special Forces commandos, he is heading for what he believes could be the greatest archaeological find of all time--the site of fabled Atlantis--while a ruthless adversary watches his every move and prepares to strike. But neither of them could have imagined what awaits them in the murky depths. Not only a shocking truth about a lost world, but an explosive secret that could have devastating consequences today. Jack is determined to stop the legacy of Atlantis from falling into the wrong hands, whatever the cost. But first he must do battle to prevent a global catastrophe.--From publisher description.
