“Write to market” is one of those pieces of advice that sounds practical, professional, and faintly intimidating. It suggests that somewhere out there are “Serious Writers” making intelligent decisions based on charts, trend reports, and mysterious publishing wisdom, while the rest of us are just blundering around hoping for inspiration. The only problem is that it’s bad advice, and “Serious Writers” know this.
Understanding the Market vs. Chasing Trends
Yes, you should understand the market. Of course you should. You should know what sort of books are selling, what readers are responding to, how publishers think, where your book fits, and what titles might be considered comparable. That's all useful. Necessary, even.
But, understanding the market is not the same as chasing trends. And chasing trends is where things go wrong. If you notice that everyone suddenly wants romantasy, or dark academia, or domestic thrillers with unreliable husbands and moody cover art, you may be tempted to think: Splendid, I shall write one of those.
That's usually the wrong move.
The main reason is brutally simple: publishing moves slowly and trends move quickly. This is true whether you're self-publishing your book or hoping a traditional publisher picks it up.
Let's say you spot a hot trend today and decide to write into it. You draft the book in six months, which would already make you faster than most writers. Then you revise it. Then you query agents, which may take months. Then, if you get one, the agent submits it to editors, which may take more months. Then, if a publisher buys it, you revise it again. Then it goes into publication schedule, which is often a year or more out.
By the time your book comes out, the trend that inspired it may already be exhausted. You're not riding the wave, you're paddling after it.
That's the first problem.
Looking for Inspiration Rather Than Imitation
The second is that publishers rarely want a copy of what just succeeded. Writers often misunderstand this. When an editor says they're looking for something "in the vein of" a successful book, they do not mean, "Please send me a weaker imitation of the exact thing I just bought." What they mean is that the successful book proved that there is an audience for a certain kind of reading experience.
If a literary thriller about glamorous fraudsters becomes a hit, the lesson is not necessarily "everyone wants another glamorous fraudster." The lesson may be that readers are in the mood for tension, reinvention, social performance, velocity, naughty behavior, and a bit of luxury. That's useful to know. It tells you something about the appetite.
But too many writers look at the successful book and imitate its packaging rather than understanding what made it desirable in the first place. They copy the wallpaper instead of noticing the architecture.
That's how trend-chasing produces books that feel second-hand. They may be competent, perfectly readable, but they often feel as though they were assembled from observation rather than written from any real urgency, fascination, or conviction. Readers can sense this, and certainly editors do.
If you're not writing something you're passionate about regardless of what you think is popular at the moment, it's unlikely to come out well.
Finding Where You Fit in the Market
A strategic writer knows ahead of time what they are passionate about writing on, from subject to genre to tone, and then asks: where does my work fit, the work I already know that I want to write? A derivative writer asks: what can I write that resembles what already sold? The first question leads to positioning (that's a good thing). The second leads to imitation (not so good).
You do need positioning. You should know who your reader is, how your book might be pitched, which recent titles overlap with it, and where it belongs on a shelf. You should be able to explain why your book makes sense in the current landscape. That's part of being professional, but none of that should replace the actual spark of the project. You still need to write a book that feels like it came from you.
This matters for artistic reasons, yes, but also for practical ones. Writing a book takes too much time to fuel it on borrowed enthusiasm. If you choose a project mainly because the market appears briefly excited about it, you're betting a year or more of your life on someone else's interest.
Your time and energy are precious and should be focused into what really matters to you, not what you think might matter to others. That's a writing lesson, but a life lesson, too.
You need enough curiosity, energy, and even mild obsession to carry you through the long middle stretch, when the idea is no longer shiny and no one is applauding. If your only motivation was "this seemed to be having a moment," you may find yourself deeply bored by page 120.
Publishers, meanwhile, are already aware of trends. They have editors, sales teams, marketers, catalogues, rights departments, and meetings full of people whose job is to know what is selling. You're not bringing them startling insight by announcing that, yes indeed, this genre appears popular. What they need from you is not trend recognition. They've got that covered. What they need is a project they can position clearly and that still feels distinct enough to deserve a place in the world.
That's where many writers get into trouble. In trying to be marketable, they file off the very edges that would have made the book memorable. In a crowded field, sameness does not make you safe. It makes you invisible.
Using the Market as a Clue, Rather Than a Command
So what should you do instead? Write adjacent to market. That's the sweet spot. And write what you want to read and will passionately enjoy writing about.
By "adjacent" I mean: understand what readers are responding to, but don't simply clone the latest success. Instead, ask where your own strongest interests, expertise, obsessions, and voice intersect with a current appetite.
If readers are responding to hidden-history narrative nonfiction, what hidden history do you genuinely care about? If they're buying practical self-help with memoir woven through it, what problem do you actually know how to help solve? If escapist historical fiction is doing well, what historical world can you bring alive in a way that doesn't feel generic or borrowed?
In my field (I write mostly about art crime), I can see that there's a new book about the Isabella Stewart Gardner Museum heist that's a hit. The last thing I should do is go and write my own book about the same heist. What it tells me is that there's a popular interest in art theft true crime nonfiction, and so I might pitch the true story of an entirely different heist.
Using the market as a clue, not a command, is a better way to think. Because the real goal is not to write whatever is currently fashionable.
The real goal is to write something that feels timely without being imitative, strategic without being cynical, and distinct without being so odd that no one knows what to do with it. That balance is where good publishing decisions live.
So yes, study the market. Read current books. Know your comps. Understand what editors mean when they say they want something "fresh but familiar." Learn how publishing works. All of that will help you enormously.
But don't ask, "What is popular right now and how can I copy it?" Instead ask, "What are readers responding to right now, and where does my own most interesting work intersect with that?" This question leads to better books. It also gives you a better chance of writing something you can sustain, finish, and stand behind.
Know the market, certainly. Just don't chase it.
