An infectious and utterly charming fictionalization of the iconic Helen Gurley Brown’s early years at the helm of Cosmopolitan, and the intrepid group of women she took under her wing to create one of the most talked about magazines of all time.

In 1965, Helen Gurley Brown, a soft spoken, self-professed “mouseburger,” is fresh off the runaway success of her book Sex and the Single Girl, a revolutionary call to single women urging them not to rush into marriage on anyone’s timeline but their own, and, even more radically, to enjoy their sex lives, gloriously free of shame. Upon the book’s publication, half the country is outraged (her mother, for one, hates the book), and the other half will follow her anywhere. Moved by the thousands of letters arriving at her doorstep from readers desperate for advice, she marches from one Manhattan magazine conglomerate to another, looking for a perch from which to dispense her unconventional wisdom. At her last stop, she finally gets her shot: just three issues to turn around the flailing magazine Cosmopolitan.

Helen quickly assembles a team of smart, savvy single girls up to the task. Soon, their lives become the stuff of magazine cover lines: the gorgeous Book Editor’s doomed romance with a man she didn’t know was married—and her bold idea for revenge. The (unofficial!) Sex Editor’s trip to soak in the world’s first champagne glass hot tub, which takes a very wrong turn. The Entertainment Editor’s clash with Joan Crawford and interview with a Park Avenue call girl that leads to unexpected revelations.

Single Girls begins at the dawn of Helen’s legendary tenure and journeys back to her youth, uncovering the devastations and people who forged her into a controversial legend. It examines how one unsinkable group of women navigated gender roles and workplace power dynamics long before these issues entered the headlines. With dazzling, high-energy prose, it captures not just a movement, but a mood: one of ambition, reinvention, and the intoxicating thrill of being young when a new world was possible for a single girl if only she was fearless enough to reach out and grab it.
