White Shark

We never thought it was really safe to go back in the water, and Benchley's new eco-thriller exploits the fear he engendered in Jaws . Here the menace is a creature spawned by a demented Nazi scientist, which has hatched 50 years later in a quiet Atlantic fishing community. Simon Chase has dropped his society wife and infant son, Max, to finish school and start the Osprey Island Marine Institute near Long Island's North Shore. Shark studies are his speciality. Chase fears the responsibilities of fatherhood, but when Max, now 12, visits, the two get on famously and soon Max has the run of the institute. Then, a crew tracking a pregnant Great White named Jaws spot a porpoise with a claw gash in its tail and see massive kills of sea life; when they then observe the same claw marks on Jaws herself, Chase knows ``there's something out there.'' Enter Dr. Amanda Macy, who studies whales using sea lions with strapped-on video cameras. Macy leases the institute, both solving Chase's money woes and making first contact with the unknown menace. Soon Macy's camera gets a shot of a steel-clawed hand grappling with a sea lion. After additional bloody encounters at sea, the beast comes ashore, eventually to threaten Amanda and Max. Benchley's writing is fast-paced, and he alternates the tension with poignant family scenes and ample amounts of marine ecology. Literary Guild main selection; major ad/promo; author tour. (June)
