In 2008, during the brief window when it was legal for same-sex couples to get married in California, perhaps no couple drew more attention than Ellen DeGeneres and Portia de Rossi.

After their wedding, photos of the couple were everywhere; DeGeneres, beaming, in a white suit and holding hands with de Rossi, the very picture of the princess bride so many young girls dream of being one day. It was a cultural touchstone, and Dietram Scheufele, a communications professor at the University of Wisconsin, says it was neither the first nor the last time DeGeneres has played that role.

On Dec. 26, 2004, Sonali Deraniyagala was vacationing with her husband, her two sons and her parents in Yala, Sri Lanka. The day was just beginning when she and a friend noticed that something strange was happening in the ocean. Within a matter of minutes, the sea had wiped out life as she had known it. In a new memoir, called simply Wave, she recalls her experience with the tsunami that killed more than 200,000 people, including her own family.

In 1963, Betty Friedan called it "the problem that has no name" and then proceeded to name it — and the name stuck. The problem was "The Feminine Mystique," which was also the title of her groundbreaking book, published 50 years ago.

Since its first publication in 1963, millions of people have read The Feminine Mystique. These days, many people read it in college — often in women's studies classes. Even so, when we talked with some young women in downtown Washington, D.C., many knew little or nothing about it.

Sometimes "the one that got away" is a book that was easy to overlook. A little gem of a first novel, or a memoir by an unknown writer that unexpectedly captured everyone's imagination.

But sometimes, it's the elephant in the room that you just haven't looked at yet. Everyone knows about it. It's one of the biggest sellers of all time. It's a cultural phenomenon — it's Fifty Shades of Grey. And I ignored it until I couldn't anymore.

They used to call it the "vanity press," and the phrase itself spoke volumes. Self-published authors were considered not good enough to get a real publishing contract. They had to pay to see their book in print. But with the advent of e-books, self-publishing has exploded, and a handful of writers have had huge best-sellers.

Earlier this year, Oprah Winfrey announced an updated version of her popular book club, this time called Book Club 2.0. Her first pick, Cheryl Strayed's memoir Wild, experienced best-seller list success thanks to what some people are calling the "Oprah bump." And last week Winfrey announced her second pick, a novel called The Twelve Tribes of Hattie by Ayana Mathis, a first-time author.
