Walker Monroe, Yale professor, librarian, and expert in ancient languages, gets an unexpected visit from two U.S. Geological Service members. They show him a piece of unknown metal engraved with a mysterious, coded text, and seek his help in translating it.
He calls in the help of his friends and colleagues, Matthew Bishop and Jennifer Porter, but unable to crack the code, they start the search for the origin of the strange piece of metal.
They take a perilous journey across four continents, unraveling a dangerous puzzle, all while followed closely by other interested parties. Piece by piece, they get nearer to a truth that will shake the foundation of everything they thought to be true about our world’s history.
