Fargo Adventures (abridged)

Treasure hunters Sam and Remi Fargo are exploring the Great Pocomoke Swamp in Delaware when they are shocked to discover a World War II German U-boat. Inside, they find a bottle taken from Napoleon's "lost cellar." Fascinated, the Fargos set out to find the rest of the collection. But another connoisseur of sorts has been looking for the bottle they've just found.

While scuba diving in Tanzania, Sam and Remi Fargo come upon a relic belonging to a long-lost Confederate ship. An anomaly about the relic sets them off chasing a mystery-but unknown to them, a much more powerful force is engaged in the same chase. Mexico's ruling party, the ultranationalist Mexica Tenochca, is intent on finding that artifact as well, because it contains a secret that could destroy the party utterly.
