How to line edit your own novel
Line editing is the pass where you stop worrying about whether the story works and start worrying about whether every line earns its place. Line editing is craft at the sentence level: does this read well, does it move, does it land.
Here are five things to watch for.
1. Not “show, don’t tell” — tell in moderation
This one gets overused because people treat it as an absolute. It isn’t.
The rule was invented for theater, where you literally cannot tell the audience what a character feels without yanking them out of the scene. A narrator stepping onstage to explain that the duke is angry breaks the illusion. So playwrights learned to show the anger: a slammed door, a curt line, a glass thrown at the wall.
In a novel, you have a narrator. Telling is part of the instrument.
The real question isn’t show or tell?. It’s will the reader have a good time experiencing this moment, or do they just need to know it happened? Your detective drives from the murder scene to the morgue. Do you show the trip? No. Nobody signed up for the commute. But if simply tell the reader there’s a murder instead of showing them the body, or explain what the medical examiner said instead of showing their reactions, the story goes flat: you’ve cut the thing the reader came for.
Show the scenes that carry weight.
2. Watch for POV slips
Whether you’re writing in close third or first person, the camera is behind one pair of eyes. Everything on the page has to be something that person could perceive, know, or think.
It’s easy to slip. Here’s one:
A dark silhouette appeared silently from behind me.
Can your narrator see what’s behind them? Can they hear silence? What they can perceive is a shadow falling across the wall they’re facing, or the hairs on their neck standing up, or the sudden feeling that someone is there. The silhouette behind them is the author’s camera, not the character’s.
These slips are small, and most readers won’t name the problem. But they’ll feel it. A POV break is a tiny crack in the immersion — a moment where the reader is no longer inside the character’s head and is instead watching from the ceiling. Enough of them, and the voice starts to feel unreliable.
But more serious than the slips in perception are the slips in opinion. Your teenager probably doesn’t have an adult’s emotions. Your main character from the Rome Empire doesn’t think the way you would.
3. Compress
This is about information density. A loose line makes the reader do more work for less payoff. A tight one pulls them through.
Compare:
There was a very old and decrepit house, and the city where it was located was quiet and heavy with mystery.
With:
In a quiet city heavy with mystery stood an old, decrepit house.
Same information. Half the words. The second version reads faster, lands harder, and — crucially — gets the reader to the next sentence sooner, which is the only place they can find out what happens.
Look for very, moderately, saw that, started to, the fact that, and any sentence where you say the same thing twice in different words. These are the low-hanging fruit. Cut them and the paragraph tightens on its own.
4. Order for escalation
Scenes have a direction. They should build, not plateau.
If your character is in a confrontation, the tension should ramp: a look, then words, then raised voices, then the thing that can’t be taken back. If the scene peaks in the middle and then levels off, the reader’s investment deflates right when it should be paying out.
The same applies to romance. Say you have a scene where your main character gives a small romantic gift to their love interest, and in the same scene they discuss a murder that happened earlier. If the gift comes first, the tenderness builds — and then collapses into a murder conversation. The scene feels like it doesn’t know what it wants.
Move the gift after the murder talk. Now the conversation is dark and heavy, and the small gesture at the end is a release — the warmth escalates out of the tension instead of crashing into it. Same material, different order, completely different feeling.
Think of it like music. You don’t put the crescendo before the bridge.
5. Trust your voice
The most important thing about a writer’s voice is that it’s theirs. The whole point of style is that it’s distinct. Hemingway’s short declaratives and Donna Tartt’s ornate layering are both excellent prose — and they’re excellent because they’re committed, not because they follow a checklist.
Refine the voice. Clean it up. Make it do what you want. But don’t sand it down until it could belong to anyone.
Line editing is slow work. It asks you to care about every sentence in a manuscript that might have three hundred pages of them. If you want a second pair of eyes — one that catches the POV slips and the loose phrasing without touching your voice — Ghostkey’s line editor does exactly that.
