The Atlantis Riddle

History isn't what we were taught. It's far more dangerous.

Book Two of the Dan Kotler Archaeological Thrillers

Two ancient stones. Two impossible moments in history. One riddle that could rewrite everything we know about human civilization.

In 1914, Thomas Edison watches his laboratory burn—and smiles. In his pocket rests a mysterious stone holding secrets far greater than any invention he's ever created.

Sixty years later, two U.S. Army officers discover a nearly identical stone amid enemy intelligence in Vietnam. With it, they'll build a corrupt financial empire powerful enough to defy even the FBI.

Today, those two stones point to the greatest lost civilization of all time: Atlantis.

Dr. Dan Kotler—brilliant archaeologist, still reeling from the fallout of the Coelho Medallion—is adrift, shunned by colleagues, and hounded by the press. When Gail McCarthy, granddaughter of a Manhattan real estate tycoon, brings him one of the stones, Kotler is pulled back into a deadly world of intrigue.

Teaming with FBI Agent Roland Denzel, Kotler races to solve the Atlantis Riddle before the stones' dark legacy unleashes chaos. 

But powerful forces will kill to keep the truth buried—and this time, the fate of Atlantis could drown the modern world.

The second explosive adventure in the Dan Kotler Archaeological Thrillers.
