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? DAN KOTLER is an independent researcher who often finds himself in more trouble than he was expecting. But when his colleague is abducted he finds himself being investigated by the FBI, he must use all of his brilliance and expertise to find her and absolve himself. ANWAR ADHAM has plans for a terrorist action on U.S. soil, and information from the Pueblo research site can give him everything he needs to put his plans in motion. Unless Adham is stopped, thousands and possibly millions will die. 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. It's an adventure that can redefine the history of America as we know it. Kotler finds himself facing off against both the FBI and Adham's terrorist network as he struggles to solve the mystery of Vikings in Colorado, to rescue Evelyn and stop Adham's plans before it's too late. “Kevin has crashed onto the action-thriller scene as only an action-thriller author can: with provocative plot lines, unforgettable characters, and enough adrenaline to keep you awake all night.” —Nick Thacker, author of 'The Enigma Strain' — HERE'S WHAT READERS ARE SAYING ABOUT KEVIN TUMLINSON'S BOOKS: ★★★★★ “[Kevin Tumlinson] is what every writer should be—entertaining and thought-provoking.” — Shana Tehan, Press Secretary, U.S. House of Representatives ★★★★★ “There was something so fascinating about [Citadel] and the cast of characters [Kevin Tumlinson] put together.” — Leah Petersen, Author of Fighting Gravity ★★★★★ "I discovered Kevin Tumlinson from The Creative Penn podcast and immediately got his novel, Evergreen.

    Cave paintings of the giant beasts hint at the profound role they played in early human culture-our Ice Age ancestors built igloo-shaped huts out of mammoth bones and even feasted on mammoth tongues. Eager to uncover more clues to this mystical prehistoric age, explorers since the time of Peter the Great have scoured Siberia for mammoth remains. Now a new generation of explorers has taken to the tundra. Armed with GPS, ground-penetrating radar, and Soviet-era military helicopters, they seek an elusive prize: a mammoth carcass that will help determine how the creature lived, how it died-and how it might be brought back to life.In this adventure-filled narrative, science writer Richard Stone follows two teams of explorers-one Russian/Japanese, the other a French-led consortium-as they battle bitter cold, high winds, supply shortages, and the deeply rooted superstitions of indigenous peoples who fear the consequences of awakening the "rat beneath the ice." Stone travels from St. Petersburg to the Arctic Circle, from the North Sea to high-tech Japanese laboratories, as he traces the sometimes-surreal quest of these intrepid scientists, whose work could well rewrite our planet's evolutionary history. A riveting tale of high-stakes adventure and scientific hubris, Mammoth is also an intellectual voyage through uncharted moral terrain, as we confront the promise and peril of resurrecting creatures from the deep past.
