I once spent three years writing a novel and roughly four minutes writing the blurb. That ratio was, to put it politely, idiotic.
The blurb is the single most important piece of text associated with your book. Not the opening chapter. Not the dedication to your nan. The blurb. It's the thing that convinces a complete stranger to part with actual money based on a hundred and fifty words. And yet most indie authors treat it like an afterthought — a quick summary banged out at midnight before hitting publish.
What a Blurb Isn't
Let's start with what to stop doing.
A blurb is not a synopsis. It's not a chapter-by-chapter breakdown of the plot. It's not the place to introduce all seven of your main characters and explain how they're connected. If your blurb reads like the back of a GCSE English exam paper, tear it up and start again.
A blurb is also not the place to tell the reader how they'll feel. "A heart-wrenching tale that will leave you breathless" isn't a blurb — it's a fortune cookie. The reader doesn't care what you think they'll feel. They want to know what the book is about, and they want to know quickly.
The Structure That Works
After years of testing, tweaking, and occasionally swearing at my laptop, I've settled on a structure that consistently sells books:
Line one: the hook. One sentence that makes the reader lean in. A question, a provocative statement, a situation that demands an answer. Something that earns the next line.
The setup (2–3 sentences). Who is the main character? What's their situation? What do they want? Keep it tight. One character, one situation, one desire.
The complication (2–3 sentences). What goes wrong? What stands between the character and what they want? This is where you create tension — the thing that makes the reader think, "Right, I need to know how this plays out."
The stakes (1 sentence). What happens if the character fails? Make the reader care about the outcome.
The closer. A short, punchy line that leaves the reader with no choice but to click "Buy Now." Often a question. Always compelling.
A Real Example
Here's the blurb I wrote for one of my bestsellers:
What would you do if you woke up thirty years in the past?
For Craig, a disillusioned forty-seven-year-old, the answer should be obvious: fix every mistake, dodge every disaster, and build the life he always wanted. Armed with three decades of hindsight, what could possibly go wrong?
Quite a lot, as it turns out.
Notice what's missing: no character descriptions, no subplots, no spoilers. It's a setup, a hook, and a promise. That's all it needs to be.
The Test
Read your current blurb and ask yourself one question: if this were written about someone else's book, would I buy it? If the honest answer is anything less than a solid yes, rewrite it. Today. Not next week. Today.
Your blurb is the hardest-working hundred and fifty words you'll ever write. Give them the time they deserve.
