The Serpent's Mound

An ancient effigy. A warning carved into the earth. A secret that will rewrite history.

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.+3

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.+4

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.+3

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.+1

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.
