How do you determine the genre of a story? Of course some stories are easily labeled but so many others seem to stand like giants with each foot on a different continent. It may be tempting to say genre doesn't matter but so many times people want or need that label. The way the review section is organized is a ready example. What do you call a victorian murder mystery that has alternative clockwork technology that makes them advanced? What about a western set in space? Or, what about a young adult romance in a dystopian cyberpunk setting with fantasy elements? The last has been a project of mine for some time. Is it the plot, the storyline, the setting, or something else that determines it? Any thoughts would be appreciated.
