The Serpent's Mound was never just a park. It was a lock.
When historian Harrison Blake uncovers a copper tablet buried within the jaws of the Great Serpent Mound in Ohio, he realizes he hasn't just found an artifact-he has triggered a doomsday device left behind by the Knights Templar.
The tablet contains an impossible cipher: a fusion of Algonquin glyphs and Latin script that points to a mystery older than the United States itself. The trail leads Harrison and his team to the Newport Tower in Rhode Island, a colonial enigma that hides a sophisticated medieval lens designed to project a map of light.
But Harrison isn't the only one hunting for the truth.
Senator Jeremiah Burke, the descendant of a shadow dynasty, will stop at nothing to keep his family's three-hundred-year-old secret buried. With a team of mercenaries and a ruthless assassin known as The Cleaner on their heels, Harrison is forced into an uneasy alliance with his nemesis, the lethal Russian mercenary Katerina Volkov.
From the burning ballrooms of the Gilded Age mansions to the freezing, flood-trapped caverns of Nova Scotia's Ironbound island, the race is on.
The Templars hid the Crown Jewels of Europe to buy a kingdom they never received. Now, the debt is due..
Can Harrison solve the geometric riddle before the Atlantic Ocean swallows the evidence-and his team-forever?
Perfect for fans of Steve Berry, James Rollins, and the National Treasure movies.
What readers are saying about the Global Treasure series: ⭐⭐⭐⭐⭐ Non-stop action and brilliant history! ⭐⭐⭐⭐⭐ Blake and Volkov are the best duo in the genre. ⭐⭐⭐⭐⭐ I couldn't put it down until the final page.
