I am writing a sci-fi novel with a female main character. My style is lo-tech, more about character development and a beautiful and unusual planet than about descriptions of technology. My target audience is women, and I am a female author. I have already decided to use a pen name, and I don't have any emotional attachment to using a female name, whatever works best.
Given these facts, what should I strive for in creating a pen name? Does a more elegant name lend itself to world-building credibility? Does a unisex name or initials still sell better in the Sci-Fi world than a female name?
