Sam and Remi Fargo, heroes of Spartan Gold, return in this extraordinary new adventure from the number-one bestselling author.

In their electrifying new adventure husband-and-wife treasure-hunting team Sam and Remi Fargo make a startling discovery that others would kill to keep hidden...

While scuba-diving in Tanzania, Sam and Remi 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.

Through Tanzania and Zanzibar, into the rain forests of Madagascar, and across the Indian Ocean to Indonesia and the legendary site of the 1883 Krakatoa explosion, the Fargos and their ruthless opponents pursue the hunt - but only one can win. And the penalty for failure is death.
