I tried an online tool that analyzed my writing, and I got this result:
I tested Juma's Rain but think results would be different for a different book. I'm quite happy with the result. For one, "Gone With the Wind", Margret Mitchell's best known book, is very well written. Also, it's a love story, as is Juma's Rain. I only tested the first scene, so getting it identified as a love story even though the love hasn't even shown up yet, it encouraging.
Try it with your own writing. It's fun,
