American Echo (Chronicles of the Cryptologist Series)

A coded letter from the American Revolution. A hidden society guarding a centuries-old secret. A truth powerful enough to fracture a nation When a mysterious 18th-century message surfaces at the Library of Congress, historian Ethan Caldwell, cryptologist Adler, and graduate student Mia Hamilton are pulled into a deadly hunt for answers. Their discovery links Dr. Benjamin Church — America’s first Surgeon General — to a covert brotherhood known as the Custodes Veritatis, whose influence has quietly shaped governments for generations. What begins as research explodes into violence when a D.C. diner is bombed, forcing the trio into a race across Vermont, Philadelphia, and Washington. Each ciphered journal and encrypted archive draws them closer to a revelation buried since the founding of the Republic. Shadowing them is Quentin Vale — “Q” — a legendary operative caught between loyalty and rebellion as the Custodes move to silence anyone who uncovers the truth. Fans of Dan Brown, Brad Meltzer, and Steve Berry will love this blend of history, conspiracy, and modern political suspense.
