The Greek Fire Cipher
A Medieval Techno-Thriller

About this book:

Constantinople burns on the horizon. The Arab fleet chokes the straits. And the empire's only salvation—a recipe for Greek Fire, the weapon that burns on water itself—lies encrypted in a dead alchemist's cipher, scattered across three lost family codes.

When a Byzantine officer smuggles the final fragment into Damascus, he doesn't seek a scribe. He seeks Ishaq ibn Malik: a scholar who reads mathematics like scripture, a cryptographer who breaks ciphers before breakfast, and a man with no loyalty to emperors. But the key to the code isn't in the text—it's in a brass mask locked inside a besieged fortress laboratory, three hundred miles of enemy ocean away.

Now two men who should be enemies ride the knife-edge of a medieval cold war: a Greek guardsman with a dagger's instinct and an Arab mathematician with a scholar's obsession. Pursued by blockading fleets, hunted by their own sides, and racing a siege clock measured in weeks of grain, they'll need every forgotten treatise of Archimedes, every trick of Al-Kindi's frequency analysis, and every ounce of trust they haven't earned. The formula is written in fire. The cipher is written in blood. And the only way out is through.
