Helen Gurley Brown, the iconic editor in chief of Cosmopolitan for thirty-two years, is considered one of the most influential figures of Second Wave feminism. Her first book sold millions of copies, became a cultural phenomenon, and ushered in a whole new way of thinking about work, men, and life. Feisty, fun, and totally frank, Sex and the Single Girl offers advice to unmarried women that is as relevant today as it was when it burst onto the scene in the 1960s. This spirited manifesto puts women—and what they want—first. It captures the exuberance, optimism, and independence that have influenced the lives of so many contemporary American women.
