Rising Tide

the long version

"In a future world where rising ocean levels swallow coastal cities and people scramble for resources on an overpopulated earth, the survival of the human race depends on biogenetic research to develop aquatic capabilities. The year is 2098, and it has never been more dangerous for the elusive Sirens to be discovered. Until now, the Sirens have remained eclipsed from the eyes of the human world, inhabiting an obscure, undiscovered island in the Indian Ocean. In a burgeoning discontent among the restless youth, the Sirens, led by a headstrong Mello Seaford, decide to test the waters of open society by striking a deal with the U.S. all powerful megacorporation, DiviniGen Inc."--Amazon.com.
