Joanna Biggs writes: “A friend of mine used to joke that women writers discovered friendship in 2015, when the last volume of Elena Ferrante’s Neapolitan Quartet came out. I laughed, but I knew what he meant. The men might not like it, but in 2023 women are overwhelmingly the ones who write, read, edit and buy books, particularly fiction. Female friendships, rather than literary marriages or bros with quills, are a force for the creation and continuation of literary culture in a way that simply hasn’t been true before.
