On 7 December 1941, four brothers exploring a shaft on a small island off the coast of Washington state make an extraordinary discovery, only to be interrupted by news of Pearl Harbour. In the present, Cabrillo, chasing the remnants of a crashed satellite in the Argentine jungle, makes a shocking discovery of his own. His search to untangle the mystery leads him, first, to that small island and its secret, and then much farther back, to an ancient Chinese expedition, and a curse that seems to have survived for over five hundred years. If Cabrillo's team is successful in its quest, the reward could be incalculable. If not . . . the only reward is death.
