Imogen — Jilly Cooper

When Imogen dashes off to the Riviera with luscious tennis pro Nicky Beresford, she is hopelessly plain and ecstatically in love. But even her total rapture can't buffer her from the shocking sight of topless tanners and other free spirits in erotic embraces.

Imogen soon discovers that St. Tropez is like one big square dance where one simply changes partners without missing a beat. She also finds that Nicky is the swiftest swapper of all.

What she doesn't know is that he has bet someone that he can deflower her before the return trip. Nor has she guessed that she won't be needing the birth control pills she smuggled past her parents--at least not for Nicky.
