The Demon Core

Forgotten secrets unleash a rising darkness in the world.

Book Twelve in the Dan Kotler archaeological thrillers 

History claims that the third and final plutonium core, intended for Hiroshima, was destroyed nearly a century ago. 

But history is wrong. 

The Demon Core has reemerged in the hands of a dangerous new power—a man consumed by vengeance and determined to bring destruction to the modern world.

When the Governor of New York is brutally murdered, the terrorists issue two chilling demands: reveal the true contents of Fort Knox to the world and force the U.S. government to step down—or the Demon Core will be detonated, wiping Washington, D.C. off the map in a fiery holocaust.

Dr. Dan Kotler, archaeologist and FBI consultant, teams up once again with his partner, Agent Roland Denzel. Together they race to uncover the suppressed history of the Demon Core and track down the man who now controls it. 

As the clock ticks down, Kotler and Denzel must piece together long-buried truths before the rising darkness consumes everything.
