It is 1943 and the world is at war. Archaeologist Lily Sampson has been sent to Trans-Jordan, by the OSS, along with Gideon Weil, the famous director of the American School of Archeology in Jerusalem. As part of their survey, they roam the beautiful, silent, Trans-Jordanian desert where the indelible presence of Lawrence of Arabia still lingers, and where the ancient Nabateans once ruled an empire from their capital in Petra. Soon Lily and Gideon are stranded in the Wadi Rum, and their Bedouin guide is murdered. When Gideon is accused of the crime, Lily must clear him of the accusation.

Lily discovers that two oil pipelines run from Iraq through the desert to the ports on Mediterranean, one through one through Trans-Jordan that supplies the Allies, the other through Syria that supplies the Nazis. Syrians and Vichy French are raiding across the border, threatening to destroy the Trans-Jordan pipeline. Lily discovers their real mission is to help safeguard the Trans-Jordan pipeline and to prevent oil from reaching the Nazis through Syria. At the same time Lily learns of a Nazi plot to kidnap and kill the eight-year old King Faisal of Iraq and take over Iraq.

Now, Lily and Gideon must act to protect the Trans-Jordan pipeline, sabotage the Syrian line, and rescue Faisal to prevent the Nazi takeover of Iraq.
