The world's oceans have become critical. Over fishing and over dumping have raised fears that nations must take steps to protect this vast global resource. Tananger, a mature bull gray whale is part of a round up in Scammons Lagoon in Baja California. Because of an extreme shortage of fossil fuels, David Parks, a "fluker", will ride in a pod on the back of the behemoth.The whale/man team head north into storming seas. They soon encounter a pirate trawler. A rogue wave, a luxurious pleasure yacht and a container ship carrying stolen toxic chemicals are drawn to a climactic point. The evil Chang Lee, leaves his Asian headquarters to take charge of an impending disaster.A strange congregation of whales pursues the pirates to Prince William Sound and then to College Fjord, the site of some of the largest glaciers in Alaska. David, Tananger and a group of Inuit fisherman confront the pirates inside the massive Harvard Glacier.The fight in ice caverns is soon brought to a halt by a major seismic disturbance a few miles off the entrance to the Sound and the threat of a tsunami looms large as fears mount of being trapped in the narrow fjord.
