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.
