Beast

Peter Benchley. First edition (stated), later printing. New York: Random House, 1991. Both unclipped dust jacket and hardcover in Very Good+ condition. 

A young couple stranded in a life raft off the coat of Bermuda. They reassure each other: There's nothing to worry about, the weather's fine, their emergency beacon is sending out a continuous distress signal. And yet, they are afraid. And they should be. For beneath their raft, something is moving. Something incredible. And savage. And huge. Peter Benchley, the man who created Jaws and other best-sellers, now gives us Beast, his most thrilling high-seas adventure yet.
