The Epsilon Book: An Archivist Adventure (Paperback) (ISBN-13: 9798263449636)

Time travel is never simple. History is fragile, and the smallest change can fracture the world.

Grady Dennison, James Callahan, and Celeste Whitlock return in a race against time to recover the Epsilon Book-a mysterious artifact whose stolen pages carry the power to rewrite history itself. From the decryption rooms of Bletchley Park to the chaos of a misdirected bombing raid, the three must navigate deception, espionage, and the shadows of the past before their adversaries can twist the timeline beyond repair.

Allies are uncertain. Enemies are hidden in plain sight. And in the heart of the Second World War, the wrong choice could doom not only the present-but the future itself.

Packed with intrigue, historical detail, and high-stakes suspense, The Epsilon Book is the gripping sequel to The Archivist, where history's survival hangs by a thread and only the daring can preserve it.
