Jessica and Elizabeth Wakefield are nearly bursting with excitement. Spring break has arrived, and the twins are off to the glamorous South of France! It's the vacation of a lifetime: Elizabeth can't wait to practice her French, but Jessica's dying to meet those romantic French boys. The Riviera turns out to be even more beautiful and wondrous than the twins had imagined, with its beach clubs, magnificent mansions, and the glittering Mediterranean Sea. But while the Frenchwoman with whom Jessica and Elizabeth are staying is a welcome hostess, her handsome son, Rene, is arrogant and rude. Can the twins figure out why Rene seems to despise them, or will he spoil their dream vacation?
