How to Write a Fair Book Review: A Reviewer's Checklist

A review is not a verdict handed down from a height. It is one reader making an argument to another, in public. The best reviews do three things at once: they tell you what the book is, they show you how it works, and they leave you able to decide whether it is for you. The worst are simply long. Whether you are writing 150 words for a shelf note or 1,500 for a literary magazine, the same handful of habits separates a useful review from an opinion with a byline.

Know What Kind of Review You Are Writing

Length changes the job. A short notice carries a judgement and one piece of evidence. A longer piece has room for context, comparison and structure, and therefore an obligation to use it. Decide which one you are writing before you begin.

Ask who is reading, too. Someone choosing their next book needs a clear sense of what it is like to read this one. Someone who has already finished it wants argument, not summary. Those are different reviews.

Declare anything that might colour your judgement: you know the author, you were sent a review copy, you are squarely in the book's target audience or squarely outside it. One honest sentence does more for your credibility than any amount of impartial-sounding prose.

Summary: Enough to Orient, Not Enough to Spoil

Readers need a handhold — genre, subject, shape, tone. Two or three lines is usually plenty for a novel; a paragraph for non-fiction, where the argument and its evidence matter more than the plot.

Set the scene, not the twists

Describe the setup freely. Handle the turning point carefully. Leave the ending alone unless the ending is genuinely the thing you are discussing, in which case say so before you begin. Genre sets the line: a revelation a literary novel's readers would shrug at can ruin a thriller. If in doubt, err towards silence, and never bury a spoiler in the middle of a paragraph.

Do not let synopsis eat the review

If more than a third of your word count is retelling the story, you have written a blurb with opinions attached. Cut it back and spend the space on the things only a reader can tell us.

Evidence Beats Assertion

"The characters felt flat" tells us nothing except that you were bored. "The characters felt flat: Marta's grief is described three times and shown once, and her sister's dialogue never leaves the register of a sitcom" gives us something to agree or disagree with. The second version is a review; the first is a mood.

Every significant claim deserves a hook. Not every sentence needs one, but if you have made five judgements and offered no specifics, the reader has no reason to trust any of them.

Ways to show your working

• Quote briefly and accurately — a phrase or a sentence, not a paragraph. Check it against the page.
• Compare, clearly framed as your comparison: against the author's earlier books, or against well-known titles in the same territory.
• Name your criteria. Pace, prose, structure, character, argument, use of sources, quality of editing. "The middle third sags" is a claim about pace; say so.
• Separate taste from fault. "I do not enjoy second-person narration" is a preference. "The second-person narration keeps the reader at a distance the story never justifies" is a criticism.

Presentation is fair to mention, briefly: typos, broken formatting, printing faults. If they are occasional slips, say that. If they are a pattern, say that instead.

Tone: Fair Does Not Mean Bloodless

A review can be sharp, funny and damning. Fairness is not politeness, and faint praise helps nobody.

What fairness rules out is contempt. Criticise the book, not the person who wrote it, and leave the author's background or identity out of it unless the book itself makes them relevant. Skip the joke that only works at someone's expense; it will be the line people remember, and not for the reason you wanted.

If a book has made you furious, write the review anyway, then leave it overnight. The anger will still be there in the morning if it was justified. What usually evaporates is the performance of anger, which is the part readers distrust.

In a negative review, do one generous, practical thing: say who might like the book regardless. "Readers who want a slow, atmospheric puzzle will find plenty here; those who want momentum will not" is more useful than a score, and it costs you nothing. And if you did not finish the book, say where you stopped. That is not a weakness. Hiding it is.

Star Ratings and the Problem of Half a Star

Stars compress a great deal into one mark, and something is always lost. The fix is not to abandon them but to define them once and apply them consistently, ideally in a line somewhere readers can find.

A workable five-point scale looks something like this:

• 5 stars — exceptional; you would press it on a friend, then ask what they thought.
• 4 stars — very good, with reservations you can name.
• 3 stars — solid and enjoyable, but not one you would rush to recommend.
• 2 stars — real problems that got between you and the book.
• 1 star — it fails at what it set out to do, or is not ready for readers.

Two cautions. Inflation first: if everything lands on four stars, the scale has stopped carrying information. Then category confusion: do not mark a cosy mystery down for not being literary fiction. Judge the book against its own intentions, then say whether those intentions were worth having. Above all, make the rating agree with the words. A review that says "clumsy prose, thin characters" beside four stars teaches readers to trust neither.

The Reviewer's Checklist

1. Have I said what the book is — genre, subject, rough shape — within the first hundred words?
2. Have I made at least two specific claims, each with evidence attached?
3. Have I named my criteria rather than gesturing at "quality"?
4. Have I quoted accurately and briefly, and checked the spelling of names and the title?
5. Have I avoided spoiling anything a reader would rather find themselves?
6. Would I be comfortable if the author read this paragraph?
7. Does the star rating match the tone of the review?
8. Have I said who the book is for?
9. Have I cut the sentences that exist mainly to show how clever I am?

Write It, Then Read It Twice

Leave the draft for half an hour and come back to it. Read it once as the author would — not to soften your judgement, but to make sure it is a judgement you meant. Read it again as a reader with a tenner and an evening to spare: do they now know whether this book is for them?

Then publish, and add a short note about how you came by the book: bought, borrowed or sent as a review copy. Disclosure costs nothing and buys the only thing a review really needs — the sense that the person writing it has nothing to hide.
