How to write a book description that makes readers want more

Guides for authors › How to write a book description

After the cover, the description is the thing that sells your book. It sits on the back cover and on every shop page, and a reader gives it a few seconds before deciding. Many authors who wrote 80,000 words with ease find these 150 the hardest. Here is how to get them right.

What a book description is for

A description has one job: to make the right reader want to start reading. It is not a summary, a synopsis or an essay about your book. It is a promise of the experience inside, written for the person who will love it.

The shape that works

The hook. One or two lines that grab attention: a situation, a question, a striking fact or a voice. Start in the middle of something.
Who and what is at stake. Who the story is about (or who the book is for), what they want, and what stands in the way.
The turn. The complication that makes it impossible to put down: the choice, the secret, the change.
The promise. One line on what the reader will get: a feeling, an answer, a journey. Then stop.

Most strong descriptions are between 100 and 200 words. If yours is longer, it is usually explaining too much.

Fiction, memoir and non-fiction are different

Fiction: lead with the character and the trouble they are in. Show the genre through the tone, so a thriller sounds tense and a comedy sounds warm. Never give away the ending.
Memoir and life stories: readers are buying a person and a journey. Open with a moment from your life, not your date of birth, and say what the story means, not just what happened.
Non-fiction and self-help: lead with the reader's problem, then say clearly what the book will help them do or understand, and why you are the right person to tell them.
Children's books: the description is usually read by a parent, teacher or grandparent. Say who the book is for, the age range, and what makes it fun to read together.

Mistakes to avoid

Retelling the whole plot, chapter by chapter.
Too many names. Two or three characters at most.
Calling your own book "gripping", "unputdownable" or "a must-read". Show it instead.
Comparing yourself to famous authors in a way readers won't believe.
Starting with background ("Born in 1952 in a small town…") rather than the moment that matters.
Spelling mistakes. They cost more sales here than anywhere else in the book.

Test it before you publish

Read it out loud: if you stumble, a reader will too. Then give it to three people who haven't read the book and ask one question: "Would you want to read this, and why?" If they can't say what the book is about, start again from the hook.

Online, only the first few lines may show before a reader taps "read more", so make sure the opening lines work on their own.

Questions authors ask

How long should a book description be?

Usually 100 to 200 words. Long enough to hook the reader and show what is at stake, short enough to read in under a minute.

Should the description be the same on the back cover and online?

It can be. Online descriptions can be slightly longer and can include a short line of praise or the author's background, but the opening lines matter most in both places.

Can I change my description after the book is published?

Yes. On most platforms you can update the description at any time, so you can improve it if the book isn't finding readers.
