Steel's 46th heartbreaker delves into the seemingly inexhaustible dramatic depths of Titanic lore, idyllic love, and delectable stars. Olivia and Victoria Henderson are beautiful, young, wealthy twins who live in upper-crust Croton-on-Hudson in upstate New York at the turn of the century. Despite their life of ease (playing tennis with the Astors, being courted by a Rockefeller), they do face the daily grind of caring for their beloved Pa, who has never recovered from Mrs. Henderson's death. Then along comes another forlorn widower, sexy Charles Dawson, whose wife perished at sea. "Damn shame she came back on the Titanic," says Mr. Henderson--who doesn't know what the Lusitania has in store for his family. As the plot thickens with the onset of World War I and the suffrage movement, Victoria--the demon seed of the dynamic duo--gets into a spot of trouble.
