In 2016, the feminist press Emily Books held a panel in Brooklyn titled, a bit cheekily, “What Is Women’s Writing?” There was no consensus, much laughter and a warm, rowdy vibe. Eileen Myles read from a memoir in progress and Ariana Reines read a poem, wearing a dress with a pattern of a city on fire. All of this felt exactly right. But even if it puts your teeth on edge to see “women’s writing” cordoned off in quotes, you can’t deny the particular power of today’s women writers — their intensity of style and innovation. The books steering literature in new directions — to new forms, new concerns — almost invariably have a woman at the helm, an Elena Ferrante, a Rachel Cusk, a Zadie Smith.
