Writing to sell or to create? The (uncomfortable) truth about commercial fiction

They’re looking at me from the shelf, right now, while I write.

On one side, I have White Noise by Don DeLillo. A masterpiece of prose, a paranoid exploration of consumer society, language and the fear of death. I’ve read it three times and each time I find something new, though I admit recommending it lightly is difficult. It’s not a “holiday‑read”.

On the other side, I have The Da Vinci Code by Dan Brown. I read it in two days, almost without breathing. Short chapters, continual cliff‑hangers, a “What if…?” (the famous high‑concept) that grabs you by the throat. The prose? Functional. The characters? Archetypes. But the pace? Relentless.

For years, like many who work with words, I lived the dilemma. Must you choose? On one side Art (with a capital A), prestige, critics. On the other side Market (with a capital M), readers, sales.

Today, as creative director and author, I can tell you with a hint of irony and plenty of pragmatism: this dilemma is, for the most part, a gigantic waste of time.

Understanding the difference between commercial and literary fiction isn’t about deciding who wins a moral prize. It’s about understanding your strategy. It’s the most important marketing decision you’ll make for your book, even before writing the first sentence.

If you get the positioning wrong, you’re done. If you sell Dan Brown as if he were Don DeLillo, the reader will feel betrayed (and bored). If you sell DeLillo as if he were Brown, the reader will feel taken in (and confused).

Today we’re not talking about art. We’re talking business, narrative architecture and how to build a story that works for the audience it’s aimed at. And yes, we’ll focus on the nemesis of intellectuals: commercial fiction. Because writing it well is damn difficult.

The great divide: what “commercial” really is?

Let’s clear up one misconception straight away. “Commercial” is not a genre. You don’t walk into a bookshop and ask for “the commercial section”.

“Commercial” is a market category. It describes books written and packaged to have the maximum appeal possible to the widest audience.

The genres that fall under this category are those we all know: thriller, mystery, romance, sci‑fi, fantasy, horror.

Commercial fiction has one non‑negotiable primary objective: entertainment. The reader buys a commercial book because they want to experience something specific: they want to feel fear (Stephen King), solve a puzzle (Agatha Christie), fall in love (Julia Quinn), escape into another world (J.R.R. Tolkien).

Key characteristics of commercial fiction

Let’s dissect the machine. What’s under the bonnet of a multi‑million‑copy bestseller?

The “hook” (High‑Concept)

This is the fundamental difference. Commercial fiction almost always relies on a “High‑Concept”. It’s an idea so clear, intriguing and original that you can explain it in one sentence. It’s the famous “What if…?”

• What if we could clone dinosaurs and build a theme park? (Jurassic Park)

• What if a professor of symbology discovered that Jesus had descendants? (The Da Vinci Code)

• What if a boy discovered he was a wizard and had to attend a secret school? (Harry Potter)

The “hook” is your promise to the reader. It’s the reason they pick up the book. Literary fiction, by contrast, is often “Low‑Concept”. Try explaining Of Mice and Men by Steinbeck in a hooking sentence. “Two itinerant workers seek employment and dream of a better future”? It’s a situation, not a hook.

Plot is king (plot‑driven)

In commercial fiction, the plot dominates. Everything—even the characters—is at the service of the storyline. Stories are plot‑driven.

The aim is to create an unstoppable chain of cause and effect that forces the reader to ask: “What happens next?”

Again, look at The Da Vinci Code. Every chapter is 3‑5 pages. Each ends with a revelation, a threat or a new question. It’s not a random stylistic choice—it’s engineering the pace.

Invisible prose (accessible language)

Here the purists wrinkle their noses. Commercial prose needn’t be “beautiful” in a literary sense. It mustn’t make us stop and admire the phrase construction.

It must be invisible.

The classic analogy is the “sheet‑glass” (windowpane) prose. The writing should be a pane so clean and transparent that the reader doesn’t even notice it; they only see the story behind it.

This doesn’t mean writing badly. It means writing in a way that’s clear, direct and evocative without showing off. The goal is full immersion. If the reader pauses to re‑read a sentence because it’s too complex (or too “artistic”), the spell is broken.

Universal themes and “relatable” characters

Commercial fiction aims at the masses. And what unites the masses? Fundamental emotions and themes:

• Good vs evil

• Love vs hate

• Life vs death

• Justice vs injustice

• Survival

• Sacrifice

The characters don’t need to be “complex” in the sense of being deeply morally ambiguous or overly introspective (like in literary fiction). They need to be relatable. We must be able to see ourselves in them—or at least understand why they do what they do.

Harry Potter isn’t as complex a character as Leopold Bloom in Ulysses. But he is universal. He’s the orphan, the outsider, the one who discovers he’s special. He’s the perfect avatar for the reader.

The other side of the barricade: literary fiction

To understand what commercial is, you must understand what it’s not.

Literary fiction doesn’t worry about pleasing everyone. Often it doesn’t even worry about pleasing. It aims to explore, challenge, illuminate.

• The hook: It’s “Low‑Concept”. The premise is often a human situation. (A dysfunctional family gathers for a funeral).

• The plot: It’s secondary. Literary stories are character‑driven (driven by the person). The focus isn’t “what happens next?”, but "why is this happening to this person?" The journey is internal.

• The prose: It’s the star. If commercial is a “sheet‑glass”, literary is a “stained‑glass”. The language is the experience. The reader expects to pause and admire the light filtering through the words.

• The themes: They’re complex, moral, often ambiguous. There’s no clear “good” and “evil”. There’s grey.

Putting these two categories against each other is pointless. It’s like asking whether a hammer or a screwdriver is better. It depends on what you’re building.

The Holy Grail: “up‑market” fiction

In recent years, publishers and agents have started using a term that, as an author, I find the most interesting of all: “up‑market”.

Up‑market fiction (or “commercial‑literary”) is the perfect hybrid. It’s the magical meeting point between the two.

Insight’s definition: Up‑market fiction takes the best of both worlds. It has the refined prose, thematic depth and complex character development of the literary, but they’re grafted onto a compelling plot, sustained pace and a strong hook typical of the commercial.

These are the books that sell millions of copies and win prestigious prizes. They’re the books that book‑clubs love because there’s “meat” to discuss, yet also a story that keeps you glued.

Perfect examples of up‑market:

• Where the Crawdads Sing (Delia Owens): A lyrical, naturalistic prose (literary) grafted onto a murder‑mystery and a love story (commercial).

• The Shadow of the Wind (Carlos Ruiz Zafón): A baroque, suggestive style (literary) that tells a gothic thriller full of mysteries (commercial).

• The Nightingale (Kristin Hannah): A war story (commercial) told with psychological depth and an attention to historical‑emotional detail (literary).

For many writers, myself included, this is the goal to strive for. It’s the perfect balance between artistic ambition and the ability to communicate with a broad audience.

Commercial architecture: how to build a bestseller (the technical part)

Ok, theory is done. Let’s get our hands into the engine. If I want to write a commercial story, where do I start?

Not with prose. Not with theme.

You start with the hook and the structure.

The world of commercial publishing, especially the American one everyone copies (yes, even Italians), is obsessed with structure. The most famous is the “three‑act structure”, popularised by screenwriting manuals like Save the Cat! by Blake Snyder.

Why from film? Because movies are the ultimate commercial medium. They don’t have time to waste.

If you’re writing commercial, I beg you to study structure. It’s not a cage; it’s the scaffolding that lets you build a skyscraper without it collapsing on the third floor.

Here’s an ultra‑simplified version, applied to a novel:

Act 1: The Setup (25% of the book)

• Setup: Introduce the protagonist in their “ordinary world”. Show their life before everything changes. Show what they’re missing (their “wound” or desire).

• Inciting incident: At around 10‑15%. It’s the event that derails normality. It’s the Hogwarts letter. It’s the murder at the Louvre. It’s the moment the plot “begins”.

• Debate: The protagonist hesitates. Do I really have to do this? It’s madness.

• Shift into Act 2 (the decision): The protagonist accepts the challenge. They embark on the adventure. There’s no turning back.

Act 2: The Confrontation (50% of the book)

This is the central part, the longest, and the one where 90% of novels fail miserably. It’s the “narrative desert”.

• Tests, allies & enemies: The protagonist explores the “new world”. They face initial challenges, meet the love‑interest, the antagonist sends minions.

• Midpoint: Exactly at the half‑way mark. It’s a crucial moment. Often a “false victory” (the hero thinks they’ve figured it out) or a “false defeat” (everything seems lost). The midpoint raises the stakes exponentially.

• All is Lost: Shortly before the end of Act 2. It’s the lowest point. The hero is defeated, alone, betrayed. The antagonist has won. It seems impossible to recover.

Act 3: The Resolution (25% of the book)

• Dark Night of the Soul: The protagonist digests the defeat. It’s a moment of final introspection.

• Climax (The Solution): Thanks to new awareness (or a new plan), the protagonist faces the final battle. It’s the direct confrontation with the antagonist.

• Ending (Resolution): The hero wins (or loses, if it’s a tragedy, but in commercial generally wins).

• Wrap‑Up: We return to a “new ordinary world”. We show how life has changed (for the better). Sub‑plots are closed.

Sounds like a formula? It is.

And that’s why it works. The reader seeks this structure, even if they don’t know it. They want it. It’s the fundamental rhythm of Western storytelling. Literary fiction may choose to break this structure, but commercial fiction lives and dies by it.

Marketing is your best friend (not a foe)

Here we are at the crucial point for a blog like this one from Insight. You’ve written your book. You’ve chosen your category. And now?

Now you have to communicate it.

The difference between commercial and literary is, above all, a matter of packaging and positioning. The cover, the blurb, the testimonials, even the font used… everything screams “commercial” or “literary”.

• Commercial cover: Human figures (often from behind), bold large fonts (often sans‑serif), high‑contrast colours, a sense of motion or mystery. Think thriller covers.

• Literary cover: Often abstract, evocative photography, an art illustration, elegant fonts (often serif), lots of white space. Think Adelphi or Einaudi covers.

The disaster happens when you mix the codes.

If you publish a slow, introspective novel about a middle‑aged professor’s crisis (literary) with a thriller cover (commercial), what happens?

The thriller‑reader buys it, expects chases and gun‑shots. After 30 pages of reflections on death, they rage and leave a one‑star review on Amazon saying “this book is boring, nothing happens!”.

Conversely, if you publish a high‑adrenaline thriller (commercial) with an abstract, minimalist cover (literary), the reader seeking a thrill… won’t even notice it. Their eye will dismiss it as “intellectual stuff”.

Understanding your category means giving your book the right tools to find its readers. You’re not “selling out” your art; you’re giving it a chance to survive.

Debunking the myths: the irony of fate

Let’s close with a bit of healthy cynicism mixed with hope, which happens to be my preferred approach.

Myth 1: “Commercial = rubbish. Literary = art.” False. There are commercial books brilliantly written (think Neil Gaiman or Tana French) and there are literary books pretentious, unreadable and poorly written. Quality doesn’t depend on category, but on the author’s talent. Stephen King was deemed “rubbish commercial” for decades. Today he’s studied at universities and won the Medal for Distinguished Contribution to American Letters. Time, sometimes, is gentlemanly.

Myth 2: “If I write commercial, I’m selling out.” This is a very Italian fear, linked to a certain intellectual snobbery. Writing to entertain, to give someone eight hours of pure escapism, is a noble goal. It’s a service. If you want to write just for yourself, keep a diary. If you decide to publish, you’re entering a market. You’re starting a conversation. It’s your duty to make it interesting for those who listen.

Myth 3: “You must choose: money or prestige.” False. Ask J.K. Rowling. Ask Elena Ferrante (who is a perfect example of up‑market: literary prose, soap‑opera‑style plot with high addiction rate). Commercial success can lead to prestige. And prestige, sometimes, leads to commercial success.

My conclusion (very personal)

As an author—and above all as a reader who reads dozens of novels—the majority of books that fail don’t fail because the prose is bad or the plot is banal. They fail because they don’t know what they want to be.

It’s a thriller that’s ashamed of being a thriller and stops every three pages to make philosophical reflections that break the pace. It’s a literary novel that feels obliged to insert a gun‑fight halfway through “to be more exciting”, betraying its nature.

My call to action, then, isn’t “write commercial”. It’s: Be honest.

Ask yourself: Why am I telling this story? What do I want the reader to feel?

If the answer is “I want them to not sleep at night for the suspense”, then study the structure of Save the Cat!, write short chapters, use invisible prose and don’t be ashamed.

If the answer is “I want them to reflect on life’s fleeting nature through the story of a man watching paint dry”, then take your time, work on the “voice” and don’t worry if the plot is slow.

But for heaven’s sake, don’t make me read about a man watching paint dry while a bomb is about to explode under his sofa—unless you’re Don DeLillo. And you probably aren’t.

Choose your battlefield. And then fight to win it.

As your creative director here at Insight, I can help you not only write the story, but also position it.

I can generate mock‑up covers for you to see whether your book “looks” commercial or literary. We can create a narrative‑structure infographic to see where your story “flattens”.

Writing is a creative act. Publishing is a marketing act. Success lies where the two meet.

Do you want me to analyse your next idea’s “hook” with you to see whether it really is high‑concept?
