    About this series

    An ancient medallion is unearthed in Pueblo, Colorado, revealing a secret that will rewrite the history of North America—the Vikings somehow made it to the continent's interior, centuries before Columbus made landfall, and there they built a city of gold. But today the COELHO MEDALLION has been stolen, and a linguist and researcher has been abducted in connection with the crime. Could the abductors be after the fabled city of gold? Or do they have a more sinister plot in mind? Whoever wins this contest of wits and wills will hold the fate of thousands in his hands, and will also lay claim to the fabled city of gold.


    TWO STONES, FOUND SIXTY YEARS APART, AND BOTH HOLDING CLUES TO WHAT MAY BE THE LOST CITY OF ATLANTIS. As academic colleagues shun him and the press hounds him, Kotler finds himself looking for a new purpose. Gail McCarthy, granddaughter of one of Manhattan’s wealthiest real estate moguls, brings an ancient stone to Kotler’s attention, he finds himself embroiled once again in intrigue, jeopardy, and mystery. This time he may uncover one of history’s oldest secrets—if he survives long enough. Working with his friend from the FBI, Agent Roland Denzel, Kotler strikes out on a quest to uncover and solve the Atlantis Riddle, and once again rewrite history as we know it.


    Famed rock-star-turned-philanthropist, Ashton Mink, is murdered in his Manhattan high-rise apartment, leaving behind the words “Devil’s Interval” as the only clue to the killer’s identify or motives. Dan Kotler, archeologist and consultant with the FBI’s new Historic Crimes Division, and Agent Roland Denzel, of the FBI, are called to the scene of Mink’s murder, and asked to help in the investigation. With the assistance of New York Police Detective, Peter Holden, Kotler and Denzel embark on another adventure, racing against the clock to solve Mink’s murder, recover stolen technology, and prevent an act of terrorism against all of humanity.

      DAN KOTLER IS BACK, AND THIS TIME HE’S TACKLING ONE OF THE OLDEST MYSTERIES IN HISTORY The second Dan Kotler archaeological thriller! 1914—Thomas Edison stands and watches his West Orange laboratory burn to the ground, taking his life’s work with it. And he smiles. In his pocket is a stone that is the key to untold mysteries, and with it he will start fresh, and create wonders beyond any of his previous work. 1974—Two US Army Special Forces officers uncover a lockbox filled with invaluable enemy intelligence that can turn the tide of the Vietnam conflict. Among the papers and maps is another stone, nearly identical to Edison’s. With this, the two officers will build a financial empire, corrupt to its core but powerful enough to elude even the FBI. TWO STONES, FOUND SIXTY YEARS APART, AND BOTH HOLDING CLUES TO WHAT MAY BE THE LOST CITY OF ATLANTIS Today—Dan Kotler, independent researcher and archaeologist, is winding down from the events surrounding the theft and recovery of the Coelho Medallion, and discovering that the fallout of this history-altering adventure reaches further than he’d imagined.

When Gail McCarthy, granddaughter of one of Manhattan’s wealthiest real estate moguls, brings an ancient stone to Kotler’s attention, he finds himself embroiled once again in intrigue, jeopardy, and mystery.
