Man had nearly destroyed the great sea creatures -- and now were they taking their revenge? A guilt-ridden Earth had turned Cachalot over to the few surviving cetaceans as a perpetual refuge -- a planet whose surface was one great ocean, where the remnants of the whales, porpoises, and dolphins could pursue their lives and perhaps even the development of an intelligence greater than man's.
Humans on Cachalot were strictly confined to a few islands and the floating towns, prospering from the wealth of the sea. The cetaceans seemed to have forgiven the thousands of years of terror and slaughter they had suffered -- some had even befriended selected humans.
But something was destroying the towns of Cachalot -- leaving no clues -- and no survivors.
This paperback is in very good condition with a light spine crease and a reader's crease.
