Common Mistakes in Book Reviews and How to Avoid Them
Anyone can post a book review. That is both the pleasure and the trap of it. A few hundred words on a book you have just finished can genuinely help another reader decide whether to spend their time and money — or it can leave them none the wiser, skimming for something solid to hold on to. The difference rarely comes down to how widely you read. It comes down to a handful of habits, and most of them are easy to fix once you can see them.
Retelling the Story Instead of Reviewing It
This is the most common fault by a distance. Four paragraphs of plot, then one breathless line at the end: "I really enjoyed this." The reader could have got the plot from the blurb in half the time. They came to a review for your judgement — what the book is like to actually read.
Two or three sentences of setup is usually plenty: the premise, the situation, where the main character stands at the beginning. After that, every sentence should be doing something else. A useful test is to ask of each one: does this tell the reader what the book is like? If it only tells them what happens, cut it or compress it.
It also helps to know the difference between setup and event. "A novel that moves between three narrators across forty years" is setup, and nobody minds hearing it. "The middle narrator dies in 1974" is an event, and plenty of readers will mind very much indeed.
Praise That Means Nothing
"Amazing." "Brilliant." "Unputdownable." "Beautifully written." They feel like praise and communicate almost nothing. "Beautifully written" can describe prose that is spare and exact or lush and overflowing — opposite qualities that appeal to opposite readers. If your review could be pasted onto any book in the shop without anyone noticing, it isn't doing its job.
The fix is to trade one adjective for one piece of evidence. Instead of "the dialogue is sharp", try: "The dialogue does the work of three pages of exposition in half a page; you learn more about the marriage from the way the two of them argue about a parking space than from any flashback." That gives a reader something they can actually use.
Honest criticism belongs here too. A review that praises everything gives the reader no way to calibrate your taste. If the pacing sags in the second half, say so, and say whether it spoils the book or merely slows it down. "The last hundred pages lose their nerve" is a real opinion. "It was fine" is not.
Reviewing the Book You Wanted Instead
It is surprisingly easy to mark a book down for failing to be a different book. A thriller gets criticised for not being a literary meditation on grief. A cosy mystery is marked down for not being bleak enough. A romance is blamed for following the conventions of romance, which is a bit like blaming a sonnet for having fourteen lines.
Ask what the book is trying to do
Two questions are worth keeping separate: did this book do what it set out to do, and did I enjoy it? Both are legitimate, but they are not the same, and readers deserve to know which one you are answering. If the writing is assured and the structure sound but the subject left you cold, that is a useful review to write — as long as you are clear about it.
"Not for me" is a perfectly good verdict. Just say why. "The humour didn't land for me" helps a reader; "it was boring" doesn't.
Spoilers, and Where the Line Sits
The line isn't only the ending. Readers care about deaths, twists, who ends up with whom, the identity of a narrator, and whether a character they like is going to be humiliated in chapter nine. A rough convention many reviewers use: material from about the first third is fair game, and beyond that you should tread carefully and warn the reader if you must go further.
Structure, though, is not the same as spoilers. You can describe how a book is built — diary entries, a fractured timeline, letters between two people — without giving anything away, and that kind of description is often the most useful thing in a review.
Building a Review That Reads Well
Many amateur reviews ramble because they were written straight through with no shape in mind. A simple structure will carry almost any book, and you can adapt it once you are confident:
- Open with a sentence or two on what the book is and who it might suit.
- Give the premise in two or three sentences. No further.
- Make two or three specific points about the writing, the characters, the pacing or the ideas — each backed by an example.
- Add one honest caveat, so the reader knows where the book wobbles.
- Close by naming the reader you would hand it to, and be specific about that.
That last step is the one people skip, and it is often the most helpful. "If you like the slow-burn tension of a domestic thriller but want it with more wit, this will suit you" does more work than a paragraph of enthusiasm.
Forgetting Who You Are Writing For
A review is not a diary entry, even if it begins as one. The person reading it is standing in a bookshop or scrolling a library app, wondering whether to commit their evening to this book. They want to know how it feels to read: its tone, its pace, how demanding it is, whether the humour is dry or broad, whether it is a book to race through in two sittings or one to read slowly.
Comparisons can help — "for readers of X" — but use them sparingly and only when they are accurate. A lazy comparison to a famous author sets an expectation the book may not meet, which is unfair on both.
A Short Checklist Before You Publish
Give the draft one read-through with these in mind. It takes five minutes and it shows.
- Is the plot summary three sentences or fewer?
- Does every piece of praise point to something specific?
- Have you said something the blurb could not have said?
- Is there at least one honest reservation?
- Would a reader who hasn't finished the book stay safe from spoilers?
- Have you named the kind of reader who would enjoy it?
- Have you cut the adjectives that could apply to any book at all?
A good review isn't a verdict handed down from a height. It is a note passed to the next reader, saying what you found and what they might. Get the habits right and that note becomes something people actively look for.
