A problem with some fantasy fiction narratives is the misogynistic treatment of female characters. The sci-fi world may still be very much dominated by men behind the scenes, but that doesn’t mean there haven’t been female trailblazers. A new book explores some of those unsung heroines. It’s called “Sisters of Tomorrow: The First Women of Science Fiction.” We talked with the author, Georgia Tech professor Lisa Yaszek. We also spoke with Bill Campbell of Rosarium Publishing, which focuses on bringing more diversity to science fiction.
