Part of Dirk Pitt®, book 17
First published 2004
Dirk Pitt discovers he has twenty-three-year-old twins he never knew existed. Summer works as a marine biologist and her brother Dirk as a marine engineer. Both inherited their father's passion for the ocean. The twins are stationed in a NUMA underwater facility off Nicaragua, investigating a mysterious brown tide that threatens marine life. Summer uncovers an ancient artifact of unknown origin. A massive storm threatens their position and a nearby luxury resort hotel. Pitt and Al Giordino race to rescue the twins and hotel guests. The storm reveals something far worse than natural disaster. The brown tide stems from human evil, part of a larger scheme that will transform the world. Summer's ancient discovery suggests the world has already changed in ways no one understands. Pitt must stop the conspiracy before its work reaches completion.
