The actress has launched an international project to distribute books in public places for people to enjoy.
Having started out in London with the Books on the Underground project, it has now spread to 26 countries around the world, from Argentina to Paris to Berlin as the Book Fairies go global.
And to mark International Women’s Day on Wednesday, Watson (who has her own book club titled Our Shared Shelf) and the rest of the Fairies distributed books by feminist authors – including Caitlin Moran and Maya Angelou.
Inside the books? A personal note from Watson herself.
