Marine explorer Dirk Pitt faces off against an elite army from an era
gone-by in order to uncover the secrets of an ancient civilization in
this #1 New York Times-bestselling series.
A group of anthropologists uncover strange inscriptions on the wall of a
Colorado mine just as an explosion traps them deep within the earth. But
their work won't stay buried long. Dirk Pitt is on hand during the blast
and quick to initiate a rescue operation. He is then tapped to lead a
research crew on behalf of the U.S. National Underwater and Marine
Agency to further study these uncanny artifacts. And that's when his
ship is set upon and nearly sunk by an impossibility--a vessel that
should have died 56 years before.
Clearly, another group knows about the relics of this long-forgotten but
highly-advanced seafaring culture. And they'll stop at nothing to keep
the rest of the world in the dark.
