A little old hat (even if our heroine is wearing a new one) gothic about Jess who goes back to Bermuda where there had been a family tragedy with a tour group, called The Jet Sets, to do some ""birding"" and play tennis. Actually she has little time for either after she's drawn into the ""vortex of something sinister"" and entertains split feelings for crippled Winston St. James, her Caliban, and the more mobile Kyre Tarkington who's into drugs. . . . All too obviously another kind of Bermuda Triangle which deserves to disappear as a sillier exemplar of the genre.
