Spartan Gold

Thousands of years ago, two superpowers of the ancient world went to war, and a treasure of immeasurable value was lost to the shadows of history.
In 1800, while crossing the Pennine Alps with his Grand Reserve Army, Napoleon Bonaparte stumbled across a startling discovery. Unable to transport it, he created an enigmatic map on the labels of twelve bottles of rare wine. When Napoleon died, the bottles disappeared-and the treasure was lost again.
Until now. Treasure-hunting husband-and-wife team Sam and Remi Fargo are exploring the Great Pocomoke Swamp in Maryland when they are shocked to discover a World War II German U-boat.
