When I first started out writing, I tried to stay nice and neatly in my lane. High fantasy? Alright then, only things that Tolkien would be proud of. Paranormal romance? Fae and vampires it is.
When I was just starting out, I didn’t realize that you could combine genres or generally be too experimental or adventurous. (Boring, I know, but we all start out somewhere).
Then I discovered Neil Gaiman and read Coraline, and my most favorite mix of genres. Horror and fantasy and comedy all at once.
I stopped staying in my lane. I wrote whatever came to mind. I’m currently writing a book that’s a combination of Sherlock and monsters and romance, horror, mythology, and urban fantasy all at once.
I guess what I’m saying is, we all start out somewhere. But it’s perfectly fine to stick with one genre or twenty. Just write good stories that make you happy.
