What Is a Synopsis?
A synopsis is a concise summary of your book that explains the main plot, characters, and ending.
Unlike a back cover blurb, which is designed to persuade readers to buy your book, a synopsis is written to inform publishers, literary agents, editors, or anyone else evaluating your manuscript.
Think of it as the complete story in a condensed format.
It covers:
-
the main characters
-
the central conflict
-
the major plot points
-
the ending
Most importantly, a synopsis is not supposed to create suspense.
Instead, its purpose is to show that your story is well-structured, coherent, and satisfying from beginning to end.
When Do Authors Need a Synopsis?
Not every author will need a synopsis, but many do.
Literary Agents
If you're seeking traditional publication, literary agents will often request a synopsis alongside your query letter and manuscript.
It allows them to quickly understand your story without reading the full book immediately.
Traditional Publishers
Publishing houses frequently ask for a synopsis during the submission process.
Editors use it to assess the overall structure, pacing, and marketability of your manuscript.
Self-Publishing
If you're self-publishing, you may never officially need a synopsis.
However, writing one is still a valuable exercise.
Creating a synopsis helps identify plot holes, weak character arcs, and pacing issues before publication.
Many authors also use it as a planning tool during revisions.
What Should a Synopsis Include?
A strong synopsis should contain the essential parts of your story without unnecessary detail.
Typically, it should include:
-
the main character
-
the primary goal
-
the central conflict
-
major turning points
-
important supporting characters
-
the climax
-
the ending
Remember that a synopsis explains the story.
It doesn't tease it.
Your reader already expects spoilers because they're evaluating the manuscript—not buying it.
Does a Synopsis Include the Ending?
Yes.
This is one of the biggest mistakes first-time authors make.
A synopsis should always reveal the ending.
Literary agents and publishers want to know how your story concludes.
Leaving out the ending or replacing it with phrases like:
"What happens next?"
or
"Will they survive?"
only makes the synopsis less useful.
A synopsis is a professional publishing document, not marketing copy.
Synopsis vs Blurb vs Summary
These three terms are often confused, but they serve very different purposes.
| Document | Purpose | Includes Ending? |
|---|---|---|
| Synopsis | Explains the complete story to publishers or agents | ✅ Yes |
| Blurb | Encourages readers to buy the book | ❌ No |
| Summary | Gives a general overview of a story or topic | Sometimes |
If you're unsure about the marketing copy that appears on your paperback, it's worth learning what to include on the back of a book cover, as that's where your blurb—not your synopsis—belongs.
How to Write a Synopsis
Writing a synopsis is often easier if you follow a simple structure.
Step 1: Introduce the Main Character
Begin by introducing your protagonist and their situation.
Readers should immediately understand who the story is about.
Step 2: Explain the Central Conflict
Describe the main problem or challenge your protagonist faces.
This should clearly establish what's at stake.
Step 3: Cover the Major Plot Points
Summarise the most important events that move the story forward.
Avoid minor subplots unless they're essential to understanding the ending.
Step 4: Reveal the Ending
Explain how the conflict is resolved.
Don't leave the conclusion open or attempt to build suspense.
Step 5: Keep It Concise
Most synopses are between one and three pages long, depending on submission guidelines.
Focus on clarity rather than beautiful prose.
Common Synopsis Mistakes
Many authors make the same mistakes when writing their first synopsis.
Common examples include:
-
turning the synopsis into a blurb
-
hiding the ending
-
introducing too many minor characters
-
spending too much time on small plot details
-
exceeding the requested length
-
using dramatic cliffhangers
Remember that the goal is clarity.
Agents and editors should be able to understand your story quickly.
Synopsis Example
Imagine you've written a mystery novel.
A weak synopsis might read like this:
"Detective Emma follows a trail of clues that lead to unexpected discoveries. But can she stop the killer before it's too late?"
This sounds exciting, but it isn't actually a synopsis.
A stronger synopsis would explain who the killer is, how Emma uncovers the truth, and how the story ends.
That's exactly the information publishers and agents need.

Conclusion
A synopsis isn't designed to sell your book.
It's designed to explain it.
By clearly summarising your plot, characters, major turning points, and ending, you'll give agents, publishers, or even yourself a much clearer understanding of how your story works.
Although writing a synopsis can feel challenging, it's often one of the best ways to spot weaknesses before your manuscript reaches readers.
And once your book is complete and ready to launch, building credibility becomes just as important as writing it. Using a book review platform for self-published authors can help you collect authentic reviews that encourage more readers to discover your work.
