How to write a book blurb
Write five sentences: who, what they want, what stops them, what it will cost, and the question left hanging. Then cut every proper noun you can, cut the resolution, and check that the first sentence works entirely on its own — because on a phone that is often all anyone reads.
The five-sentence draft, then eight cuts
Write the five. Then apply the eight. It takes about forty minutes and beats staring at a blank page for three weeks.
- Sentence 1: who this is about, and one thing that makes them specific.
- Sentence 2: what they want, or what has just happened to them.
- Sentence 3: what stands in the way.
- Sentence 4: what it costs if they fail — the stakes, made concrete.
- Sentence 5: the question the reader is left holding. Stop here.
- Cut: every proper noun beyond two.
- Cut: every event that happens after the first quarter of the book.
- Cut: any sentence explaining what the book is 'about' thematically.
- Cut: adjectives doing the work verbs should do.
- Add: one unambiguous signal of tone — funny, bleak, warm, tense.
- Add: for non-fiction, one line of credibility. Short.
- Test: does sentence one work with nothing after it? That is what a phone shows.
A separate free preview: A free outside view of your own pages
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. Send up to 5,000 words. You get back what the draft appears to be doing to somebody who wasn't there when you wrote it, the strongest thing in it named, the exact place a reader starts to drift, and three revision priorities in order.
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. An AI-assisted read of your own pages. Not a human edit, not a line edit, and not a scored report.
Start badly, on purpose
The blurb that arrives fully formed does not exist. Write the five sentences plainly and clumsily — A widowed farmer in Donegal finds a suitcase of letters — and fix them afterwards.
Most authors get stuck because they try to write the finished, evocative version first. That is like trying to type a sentence in the right order. Get the structure down, then make it sound like something.
Cutting the plot is the whole craft
Your instinct will be to include the turn on page 180, because it is the best thing in the book. That is exactly why it must not be in the blurb.
The rule of thumb: nothing beyond the first quarter of the book. Whatever your inciting incident is, the blurb stops shortly after it.
This feels like withholding. It is: that is what a blurb is for.
Write for the phone, not the paperback
The blurb will mostly be read as a product description on a phone screen, with three lines visible before read more.
So: strongest sentence first, short paragraphs, a break every two or three sentences, no dense block. Bold sparingly if the platform allows it, and only on a line that would earn a click.
Then look at it on an actual phone, in the actual listing, next to actual competitors. Almost nobody does this, and it takes ninety seconds.
Testing it on real people
Read it aloud to someone who has not read the book. Then ask them three questions: what kind of book is this, who is it for, and would you read on?
If they cannot name the genre, add a tone signal. If they say it sounds interesting in that particular voice, the stakes are not concrete. If they ask what happens next — you are done.
Do this with three people who read your genre. It is the cheapest market research available and it takes an afternoon.
About Your Book Pro
Your Book Pro is a book-writing platform built in Britain. Start with an idea, notes, half a draft, a podcast, or a finished manuscript, and use our purpose-built AI tools for planning, feedback, editing, proofreading, cover designs, and to create print-ready files. Writing is totally free: you can type, upload or speak your book as much as you like, and use only the editing tools you need with Plus, or go unlimited with Pro.
Produce world-class drafts at the fraction of the cost of hiring a human editorial team.
Every account starts with 1,000 welcome credits, and a plain export of your own words is free.
Each guide says plainly when a person does the job better than AI. Guides on legal topics are general information, not legal advice.
Back-Cover Blurb works from your actual manuscript rather than from a description of it, which matters — the blurb you would write from memory is usually about the book you intended, and the manuscript knows what you wrote. It produces several variants in your genre's conventions so you have something to react to, which is far faster than generating from nothing.
Use it alongside Generate a Cover so the front and back are speaking to the same reader, and after Detailed Editorial Feedback if you are still unsure what the book is really about — a blurb that is hard to write is very often a symptom of a structural question that has not been settled.
And if the budget allows, a human blurb copywriter at £100–£350 is genuinely good value for a book with commercial ambition. Arrive with three drafts and you will get better work for less.

- What tense should a blurb be in?
- Present tense for most fiction — it creates immediacy. Past tense is normal for memoir and history. Be consistent; mixing them is a common and jarring error.
- First person or third?
- Third for most fiction, even when the book is first person. Memoir and self-help often work in first. What matters is that it does not read like a character speaking unless that is a deliberate effect.
- Should I mention the book's themes?
- Rarely, and never as an abstract noun. 'A story about grief' tells a reader nothing they want. Show the situation and let them infer the theme, which they will.
- How do I write a blurb for a memoir?
- Situation, why this life, what the reader will come away with. Memoir blurbs are permitted to be more direct about emotional territory than fiction blurbs, and readers expect that.
- Can I change the blurb after publishing?
- Yes, on all the main platforms, within hours. Blurbs are the easiest thing to A/B test after launch, and a book with flat sales and a weak blurb is worth one more attempt before you conclude anything.
