内容简介：
In the very near future, Dr. Maria Cruz and her team of genetic researchers working for AquaGen develop a method of implanting stem cells in humans that will allow them to grow functional gills. Brad Logan and his Navy Seal team volunteer to be the first to undergo this procedure, which will allow them to explore the deepest, least known portions of the Earthas oceans. Brad and his team encounter new and unusual life forms beneath the ocean and are soon involved in several research projects that include early detection of tsunamis, tracking whales and even efforts to protect endangered populations of sharks. The discovery of a new strain of bacteria on the ocean floor puts the dive team and research scientists in a deadly confrontation with OPEC and private oil companies.
