Your writing may vary wildly in style and scope. You may find yourself jumping genres or target audience, veering between contemporary and sci fi, or middle grade and adult. But if you take a moment to stop and have a good look at your writing projects—all of them, published or unpublished, polished or abandoned—you’ll most likely find a common thread. A theme (or two, or three), winding through all of those different projects and connecting them back to you, heart and soul.
About a month ago, I tweeted the following:

It was a jokey post, obviously, but there was a grain of truth in there, nevertheless. Who am I? Pretty much everything I’ve ever written contains something about identity and our place in the world. It could be literal, like in my YA novel Heart Blade, where my main protagonist has no memory of her previous life and is trying to find out where she fits into her new one. It could be a more subtle approach, such as in my short story The Sugar Cane Sea (Not All Monsters anthology, Strangehouse Books), where the main character is on the run from her abusive and demonic husband, and won’t be able to make a life of her own until she’s free.
Identity and belonging have always been recurring questions in my own life, ones that bubble up every few years but are always there, waiting under the surface. In my case, this was due to being a child of two cultures, born in one country and then, at the age of eight, moving to a different one, vastly different to the first. Of course, years later I complicated matters by moving to the USA and having a whole new set of identifiers thrown at me…
And so, even without meaning to, I find those questions echoed in my writing.
When I mention recurring themes, I’m not talking about that elusive thing called ‘author voice’. That’s something separate, which has to do with writing style more than anything. But themes in writing and author voice are, at the same time, entangled to a certain extent. Just as you can usually recognize your favorite author’s way with words (even when they cross the genre streams or write for a different market), you can probably pick out certain themes you’ve learned to associate with that author, and which emerge time and time again in their books. And often there’s a sweet spot where the author’s voice and their themes meet to create a unique brand that’s all their own.
No one has to have recurring themes in writing. But I don’t think most of us plan these things. They just happen, as our words on the page draw upon the subtleties of our innermost thoughts. Chances are, you have certain themes that crop up over and over in your own work, too. So take a moment to think back on some of your writing. Dig beneath plot and message to get at the bones of the work—the underlying themes that color the story. And if you find you have a few (or many) in common, weaving their way through your different projects? It won’t change your work, or writing style. But it just may help you come a little closer to understanding who you are—not as a writer, but as a person.
