A father and son team wrote this book, and a father and son team serve as the protagonists of this undersea thriller, part of the Dirk Pitt series. A World War II plan by the Japanese to depopulate the U.S. with a Chinese biological weapon launched via submarine is linked to a 2007 scheme by a South Korean to detonate a rocket full of viruses in Los Angeles and frame Japanese terrorists for the deed. Its up to Dirk Pitt Sr. and Jr. to foil the past and near-future plots.
