Lost empire
(Book)

Through Tanzania and Zanzibar, into the rainforests of Madagascar, and across the Indian Ocean to Indonesia and the legendary site of the 1883 Krakatoa explosion, husband-and-wife treasure-hunting team Sam and Remi Fargo and their ruthless opponents pursue the hunt for a relic--but only one can win. And the penalty for failure is death.

Discovering a Confederate relic during a diving expedition in Tanzania, Sam and Remi Fargo learn of the existence of a second artifact that is being ruthlessly sought on multiple continents by a fast-rising Mexican political party.
