Near the island of Antikythera, off the southern coast of Greece, sponge divers discover a 2,000-year-old Roman shipwreck that harbors secrets potentially catastrophic to the public image of Greece. The government of Greece and two criminal organizations will stop at nothing to seize the documents...the criminals to sell them, the government to destroy them. Visiting Harvard classics professor Tobias Romulus Finch becomes the unwilling guardian of the documents, his life now dependent upon finding a solution acceptable to both opposing forces.
