A New York Times BestsellerLong hailed as the grand master of adventure fiction, Clive Cussler has continued to astound with the intricate plotting and astonishing set pieces of his novels. Now, with a surprising twist, he gives us his most audacious work yet.Dirk Pitt recently discovered that he had two grown children - twenty-three-year-old fraternal twins born to a woman he thought had died. Both have inherited his love of the sea: the girl, Summer, is a marine biologist; the boy, Dirk, is a marine engineer. And they are about to help their father in the adventure of a lifetime. A brown tide is infesting the ocean off the shores of Nicaragua. The twins are working in a NUMA(r) underwater enclosure, trying to determine its origin, when two startling things happen: Summer discovers an artifact, strange and beautiful and ancient; and the worst storm in years boils up out of the sky, heading straight for them - and for a luxurious floating resort hotel.About the author: Cussler's books are published in more than 40 languages in more than 100 countries with a readership of more than 125 million avid fans.
