When a hero whose name never appears in print without a registered trademark symbol beside it sets out on a new adventure, readers should know what to expect: a great deal of derring-do, outlandish adventures, and fantastical scenarios. For Dirk Pitt, reality is an inconsequential construct. What matters is the U.S. National Underwater and Maritime Agency (NUMA) superhero's unflagging energy, wit, strength, sex appeal, and patriotism. In this tale of a Chinese billionaire who plans to divert the mighty Mississippi in order to expand his illegal smuggling ring, find a treasure lost at sea nearly half a century ago, and, incidentally, split the U.S. into three countries controlled by China, Cussler's American version of James Bond struggles to save the day.
