Spanning generations from the 1930s to the present day, The Babylon Code tells a true story of discovery. Arriving in Cairo on the eve of the Second World War, Danielle Dawson has been assigned her first mission as a spy. But when the German double agent she recruited is murdered, she learns that a mysterious book the agent had given her has a treasure map hidden inside. Embarking on a dangerous journey to Beirut, Damascus, and Babylon, Danielle must learn the map’s secrets to stay alive.

More than eight decades later, Danielle’s grandson Sam Romero is a professor of antiquities law spending his summer on an archaeology project in Italy. Detained by police as a witness to a theft from the Vatican’s secret archive, Sam learns that the stolen map had belonged to his grandmother Danielle. Chased by assassins, he races across Rome to the ruins of Petra and the Judean desert. Could it possibly be true, he wonders, that the map now in his hands reveals the fate of the world’s greatest lost treasure?
