"Sayonara. The world's largest liquid natural gas tanker is a huge risky investment for Heritage Mariner. Crewless and programmed to dock automatically in Japan, using only computer control and millimetre-precise GPS positioning, Sayonara's cargo has the potential of fifty-five atom bombs, which will power the construction of the floating city of Kujukuri, thirty-five miles west of Tokyo. But disaster strikes when a group of pirates hijacks the vessel four days before docking, breaks into its secure areas, hacks the computers and takes control. Richard Mariner has ninety-nine hours to assemble a team and retake Sayonara in a desperate, danger-filled race against time to prevent a deadly impact with cataclysmic consequences. "--Back cover.
