As the threat of European war looms, the Kingdom of Ethiopia is one of the first to come under attack from the Fascist powers. When Dr. Jerry Ballard's long-anticipated dig in Alexandria is interrupted by the arrival of his old friend Iskinder on a secret mission for the Ethiopian Emperor, Jerry has to make a stand-even if it means delaying his dream of finding the lost tomb of Alexander the Great. Fortunately, the rest of the Lodge, Alma, Lewis, Mitch, and Stasi are in Sicily showing the Catalina flying boat at a prestigious European air show. Bound by oaths and friendship, they undertake a dangerous journey across the Mediterranean and into the heart of a battle where they will be tested as never before.
