The Coelho Medallion - Dan Kotler, #1

History is about to get dangerous.

Book One of the Dan Kotler Archaeological Thrillers

An ancient medallion unearthed in Pueblo, Colorado, rewrites the history of North America: Vikings reached the continent's interior centuries before Columbus—and built a city of gold.

When the Coelho Medallion is stolen and a researcher abducted, Dr. Dan Kotler—brilliant anthropologist who attracts trouble like a magnet—finds himself as the FBI's prime suspect. To clear his name and rescue his colleague, Kotler must follow the artifact's trail into a secret that could upend everything we know about the New World.

But he's not the only one hunting it.

Terrorist Anwar Adham needs the medallion's secrets to launch a devastating attack on U.S. soil. If he succeeds, millions will die. 

Whoever claims the medallion will control the fate of thousands—and lay claim to a lost city of gold hidden for a thousand years.

Now Kotler is caught between federal agents who want him behind bars and a ruthless terrorist network that wants him dead. Racing across the American heartland, he must solve the mystery of the Vikings in Colorado, save his friend, and stop a modern-day apocalypse—before the past destroys the present.

The explosive first adventure in the Dan Kotler Archaeological Thrillers.
