If you try to be something you're not, sometimes the results can be ridiculous:
Yeah, that's a dog.
As much as this dog's owner wants it to look like a camel, the essence of dogginess is still there.
Now, a lot of people will think this is wrong. But I'm of two minds on it. On the one hand, it obviously lacks authenticity. There's a basic dishonesty about it. (Plus, it probably embarrasses the dog. Give the dog a piece of bacon, though, and it'll likely get over it.)
On the other hand, a part of me kinda likes the whimsy. I think the world could use more whimsy.
If we twist our brains a bit, I'm sure there's something here we can apply to writing fiction.
*twist, twist, twist*
When you're true to your voice -- whether you're literary or hard-boiled or funny or erotic, or whatever -- then I think your readers pick up on the underlying "you-ness" and are more comfortable. More willing to suspend that disbelief for the brief time they spend with you. So it helps to know what you are, and make the most of it, instead of warping your work-in-progress into the genre du jour.
But maybe you're just a born camel-dog kind of writer. Maybe that's what comes naturally to you. In which case I say...
EMBRACE THE WHIMSY!
Just don't feel like you have to write a literary-inspirational-vampire-zombie-erotic police procedural to make your book stand out. Unless that's YOU. (And if it is, let's talk. Because I really want to read your book.)
If you write, what's the most comfortable fit, genre-wise, for you?
(Which isn't always easy to pin down. Believe me, I know. For the longest time I thought I was writing funny paranormal mysteries, but it turns out they're light urban fantasies. Hey, I just write 'em. I let the pros categorize 'em.)
If you're a reader (as I strongly suspect you are; otherwise, really, why would you be here reading this?), is there a book that's drawn you in despite being a genre you normally don't salivate over*? What was it about the book that worked for you (if you can pin it down)?
*Note the clever doggy reference to tie up this blog post. You know, Pavlov's dog? The salivating thing? The way that...oh, never mind. Trust me. It works.
