The Forgotten Rune

History may shield us from a universe of horror.

Book Thirteen in the Dan Kotler archaeological thrillers 

A mysterious artifact holds the key to unraveling the mystery behind a senator's disappearance—but it may be humanity's greatest threat.

When Dr. Dan Kotler is recruited to decipher a strange rune unearthed at a controversial archaeological dig site in Turkey, he quickly realizes the stakes are far higher than anyone imagined. 

The site suggests an age of humanity far older than mainstream science is willing to accept, while the rune itself hints at a universe far stranger and more dangerous than anything we have ever encountered.

As Kotler races to solve the enigma of the forgotten rune, he uncovers a trail of disappearances—including a U.S. senator—that leads straight into the heart of the mystery. 

The power locked within this ancient symbol may be more than humanity is ready to handle, and Kotler, along with his FBI partner Agent Roland Denzel, must decipher its secrets before it unleashes forces that could reshape—or destroy—our world.
