It won’t surprise those who remember Cussler’s Raise the Titanic! (1976) that he now uses the 1956 sinking of the Andrea Doria as the springboard for another thriller involving the National Underwater and Maritime Agency. According to Cussler, the Andrea Doria sinking was deliberate, but that secret begins unraveling two generations later, when archaeologist Nina Kirov, fleeing a “terrorist” attack on her dig, is rescued by a NUMA vessel. Aboard are Kurt Austin and Joe Zavala, NUMA field operatives equally deft with underwater hardware and the ladies. The pair’s first job is standing off the “terrorists” pursuing Kirov. Plots–not to mention counterplots–rapidly thicken as NUMA squares off against Halcon, who is clearly a descendant of Fu Manchu despite his Latino characterization. Halcon seeks an immense treasure, brought by fleeing Carthaginians to the Mayan empire, to finance an independent Latino nation in the U.S. Southwest. Before Halcon is defeated, Cussler dispenses, with new collaborator Kemprecos’ aid, the fast action, larger-than-life characters, less-than-graceful prose, credulity-stretching scenarios, and high-saltwater content that are his trademarks. A superlative subplot relays the adventures of archaeologist Gamay Trout and her companion, the Mayan Dr. Chi, as they try to escape outlaws, Halcon’s minions, and the natural hazards of the Yucatan Peninsula. Likely to prove eminently satisfactory to Cussler fans.
