How to Write a Synopsis: What to Include and What to Skip, With Examples

You have finished the novel. You have queried a handful of agents. And then one of them asks for something you were not quite ready for: a synopsis.

Suddenly the manuscript you spent two years shaping into three hundred pages of tension and payoff needs to fit onto a single sheet of paper, and it needs to say everything, including the ending. Most writers freeze at this point, because everything they have been taught about marketing a book tells them to protect the twist, hold back the resolution, and leave the reader wanting more. A synopsis asks for the opposite.

This is the one document in a submission package that rewards you for spoiling your own story. If that sounds strange, it is because most of the advice floating around online conflates the synopsis with a blurb, or with the story paragraph in a query letter, or with a book report from school. None of those comparisons hold up, and the confusion is exactly why so many writers submit a synopsis that undersells their book.

At EU Publishing House, we have read through submission packages, sat with writers while they untangled their own plots, and watched agents skim a page in under a minute before deciding whether to read further. This guide walks through what a synopsis actually is, what belongs in it, what needs to be cut, and a simple numbered method that turns a blank page into a finished draft. You will also find a comparison table, an include and skip checklist, an annotated example, and genre specific guidance for romance, thriller, mystery, and literary fiction.

By the time you reach the end, you will have a repeatable process you can use for this manuscript and every one after it.

What a Synopsis Is and Why It Matters

A synopsis is an industry document. It exists to show an agent or editor that your narrative arc holds together from the first page to the last, including the ending. It is not a piece of marketing copy, and it is not written to entice anyone. It is written to prove something: that your plot has a shape, that your character changes, and that the story resolves in a way that makes sense.

Agents and editors read a synopsis the way an engineer reads a blueprint. They are checking whether the structure is sound. Does the inciting incident actually incite anything? Do the middle plot points connect to the ending, or do they wander? Does the protagonist end the story changed from how they started? A synopsis answers those questions in a page or two, without any of the atmosphere or suspense that made the manuscript enjoyable to read in the first place.

That distinction matters because writers who approach the synopsis as a sales document tend to write something vague, moody, and short on detail, exactly the opposite of what the page is for.

It also helps to separate a synopsis from the concept of a premise. Your premise is the single sentence idea underneath the whole book: a widow discovers her late husband's second family, or a courier smuggles memories across a border where feeling is illegal. A synopsis builds outward from that premise into the full sequence of events that follow it. If you are still refining that one sentence idea before you tackle the longer document, our guide on what a story premise actually is is a useful place to start, since a wobbly premise tends to produce a wobbly synopsis no matter how carefully you follow the structural rules below.

The Spoiler Document Reframe

Here is the reframe that changes how most writers approach this task: the synopsis is the spoiler document. Revealing the ending is not a mistake. It is the entire point.

Think about why. An agent reading your query letter has already been hooked by the premise. They requested the synopsis because they want proof that the premise pays off. If you hide the ending, hedge on the resolution, or leave a twist dangling, you are not creating suspense. You are signalling that the plot might not actually hold together, and that you are hoping nobody checks.

Writers who have spent years training themselves to avoid spoilers in marketing copy often find this the hardest habit to unlearn. But a synopsis that withholds the resolution reads as evasive, not intriguing. Say what happens. Say how it ends. Say what changes for your main character. That is what the page is for.

The Agent-Eye View: What Gatekeepers Scan For

Agents typically read a synopsis in well under a minute during the first pass. That is not because they are being careless. It is because a well-built synopsis makes its structure obvious at a glance, and an experienced reader can spot that structure quickly.

Here is what they are scanning for, roughly in this order:

• Who the protagonist is at the start, along with their core want or need.

• The inciting incident that knocks the story into motion.

• The major plot points, laid out in chronological order.

• The twists and how they escalate the stakes.

• The ending, stated plainly.

• The change in the protagonist from beginning to end.

If any of those six elements are missing or buried under description, the synopsis fails its job even if the prose itself is polished. This is worth repeating because it is the single most common failure point: agents are not grading your sentence craft here. They are checking whether your story spine is visible and intact.

Synopsis vs Blurb vs Query Letter Story Paragraph

One of the fastest ways to sink a synopsis is to accidentally write a different document instead. The synopsis, the blurb, and the query letter's story paragraph get confused constantly, because they all summarise the same book. But they have three different jobs, three different audiences, and three different rules about what to reveal.

Three Documents, Three Jobs

A synopsis is written for an agent or editor, after they have already expressed interest. Its job is to demonstrate that the full plot works, ending included. A blurb, sometimes called back cover copy, is written for a potential reader browsing a shelf or a retail page. Its job is to entice a purchase, which means it deliberately withholds the resolution. A query letter's story paragraph sits between the two. It hooks an agent within the first few sentences of a cold pitch, summarising the premise and the stakes, but it stops short of the ending, because its job is to earn a full manuscript request, not to prove the whole plot out.

Side by Side Comparison

Document	Primary purpose	Typical length	Reveals the ending	Tone
Synopsis	Show the full narrative arc and ending to prove the story works; an industry document for agents and editors	500 to 1000 words, one to two single-spaced pages	Yes, including every major twist	Neutral, factual, matches the manuscript's energy without sales language
Blurb / back cover copy	Entice a reader to buy; marketing copy	Varies by platform and genre; always check current retailer and publisher guidance before finalising	No, withholds the resolution	Punchy, sales oriented, may use rhetorical questions
Query letter story paragraph	Hook an agent and summarise the premise and stakes in a handful of sentences	Varies by agent; always confirm each agent's stated preference	No, hints at stakes without resolving them	Compelling, concise, voice driven, professional

Length conventions for blurbs and query paragraphs shift depending on platform, genre, and individual agent preference, so treat the ranges above as a starting point rather than a fixed rule, and check current submission guidelines before you finalise either document.

How to Use This Comparison When Drafting

Keep this table open while you draft, and use it as a diagnostic tool. If you notice yourself withholding the ending, you have drifted into blurb territory. If you are hooking without laying out the full plot, you are writing a query paragraph. A synopsis reveals every twist and the ending, in full, every time.

Length and Formatting Guidelines

Default Length: 500 to 1000 Words, One to Two Pages

The standard default for a fiction synopsis is 500 to 1000 words, single-spaced, running to one or two pages. That is a tight container for an entire novel, which is exactly why the numbered method later in this guide is worth learning properly.

Guidelines vary by agent and by genre, so always check the specific submission page before you send anything. Some agents ask for a strict one-page limit. Others will accept up to three pages for a complex, multiple point of view manuscript. When no length is specified, default to the 500 to 1000 word range and stay on the shorter end if you can.

Page Layout and Contact Information

A properly formatted synopsis page follows a few consistent conventions:

• Contact information sits in the upper left corner: your name, email, and phone number.

• The manuscript title and genre are centred below the contact block, often in a slightly larger or bolded font.

• The body text is typically double spaced, matching standard manuscript formatting, unless an agent specifically requests single spacing.

Picture a page with your name and email tucked in the top left, the title centred beneath a small gap, and the body starting a few lines down. That visual structure alone tells an agent you understand submission conventions before they read a single sentence of plot. If formatting your submission package feels like its own project, our formatting service handles exactly this kind of detail work.

Voice, Tense, and Character Name Conventions

Write in third person present tense, even if your manuscript is in first person or past tense. This is a synopsis convention, not a reflection of your novel's actual point of view. Memoirists are the exception; first person is acceptable for a memoir synopsis, and either choice works depending on how personal the framing needs to feel.

When a character appears for the first time, put their name in capital letters. MIRA VOSS. TOM ARCHER. This convention helps an agent track a growing cast without flipping back to reread earlier paragraphs.

State character traits directly rather than dramatising them through scene. Instead of showing a character flirting nervously across three sentences, simply write that she is a hopeless romantic who avoids conflict. A synopsis has no room for demonstration; it has room for statement. If naming a trait precisely is proving harder than it should, a list of adjectives that describe a person can help you land on the exact word instead of settling for something vague like "nice" or "complicated," neither of which tells an agent anything useful about how the character will behave under pressure.

Dialogue and Tone

Use dialogue sparingly, or skip it entirely. When a character says something plot-critical, paraphrase it rather than quoting it directly. Every line of quoted dialogue costs you space that could otherwise carry plot or motivation. This applies even to a line you consider the emotional heart of the book; the temptation to preserve  famous or pivotal quote from your own manuscript intact in the synopsis is understandable, but a paraphrased version that captures the meaning in half the words almost always serves the document better.

Match the tone and energy of your manuscript without slipping into sales language or rhetorical questions aimed at the reader. A thriller synopsis should feel tense. A literary novel's synopsis should feel considered. But neither should ask, "What would you do if your sister disappeared?" That question belongs in a blurb, not here.

This is also where writers sometimes overcorrect in the opposite direction, stripping every trace of style out until the page reads like a legal document. A small amount of figurative language is fine if it echoes your manuscript's actual voice, but it should never replace a plain statement of what happens. One well-placed image beats three paragraphs of atmosphere that never quite say what occurs.

Tailoring Length to Agent Guidelines

Every agent's submission page is slightly different, and treating the 500 to 1000 word default as a hard rule rather than a starting point is a common mistake. Before you submit, check the specific guidelines for each agent or editor on your list, and adjust length and spacing accordingly. Keeping a master version at around 750 words gives you a flexible base you can trim or expand as each submission requires.

What to Include in a Synopsis

Protagonist and Motivation at the Start

Open by establishing who your protagonist is before the story begins, along with their core want and the thing standing in their way. Two or three sentences is usually enough. This single opening move gives an agent a reason to keep reading, because a story without a want has no engine.

If you find yourself unsure how much personality detail belongs in that opening, it helps to think in terms of what actually makes a character function on the page rather than what makes them feel real to you as the writer. Our breakdown of what makes a fictional character work walks through the difference between traits that exist purely for flavour and traits that drive decisions, which is exactly the distinction a synopsis needs you to make quickly.

Inciting Incident and Major Plot Points

Once your protagonist and their situation are established, move immediately into the inciting incident: the event that knocks the story out of its resting state. From there, lay out the major plot points in chronological order. Every turning point that changes the direction of the story belongs here. Every scene that simply builds atmosphere or backstory does not.

If you are unsure whether an event counts as a major plot point, ask whether removing it would break the logic of what follows. If the answer is no, cut it.

Twists and the Ending

State every major twist plainly, and state the ending in full. This is the section where writers most often flinch, because everything in their training as a storyteller says to protect the reveal. Resist that instinct here. An agent needs to see that your twist is earned and that your ending resolves the story's core tension. Vague gestures toward "a shocking discovery" without saying what that discovery is will read as a red flag, not a hook.

Many strong twists rely on some form of dramatic irony, where the reader or a character eventually sees the truth that another character has missed all along. If your manuscript builds a twist this way, state the reveal directly rather than describing the misdirection that led up to it; our guide to irony in literature is worth a look if you want to understand why a well-built twist tends to feel inevitable in hindsight rather than random.

Character Arc and Change

Show how your protagonist is different at the end than they were at the start. This does not need to be a separate paragraph; it can be woven into your final sentences describing the ending. But it needs to be explicit. A story where the protagonist ends up exactly where they started, with no internal shift, reads as static even if the plot events themselves were eventful.

The Story Spine: What to Keep

Everything you include should serve the story spine: the chain of cause and effect that runs from the inciting incident to the ending. Subplots, secondary romances, and minor characters who do not move that spine forward should be left out entirely, even if they are important to the emotional texture of the full manuscript.

If you are working out how a secondary character fits into the larger structure of your cast, our piece on protagonist versus antagonist breaks down which roles actually drive plot and which ones support it from the sidelines.

Include and Skip Checklist

Use this table as a line-by-line audit tool once you have a draft. Go through your synopsis and check whether each row on the left appears, and whether each row on the right has been removed.

Include	Skip
Protagonist and motivation at the start	Subplots and minor characters
Inciting incident	Excessive backstory
Major plot points in chronological order	Extended dialogue
Twists and the ending	Thematic commentary
Character arc and change	Rhetorical questions
Main characters only	Sales language
Story spine events	Chapter by chapter summaries

This checklist doubles as a mistake audit later in the process, so keep it handy through several drafts rather than treating it as a one time exercise.

What to Skip in a Synopsis

Subplots and Minor Characters

Every manuscript has subplots that matter enormously to the reading experience: the best friend's side arc, the slow burn romance running underneath the main plot, the family history that colours everything. None of it belongs in the synopsis unless it directly changes the outcome of the main plot. Keep only the spine and the characters who drive it.

Excessive Backstory and Extended Dialogue

Backstory that explains why a character behaves a certain way is often essential to the manuscript, but a synopsis has no room for it beyond a single clarifying phrase. If backstory is genuinely load-bearing for the plot, state its outcome directly rather than narrating how it unfolded. The same logic applies to dialogue: paraphrase what was said, and save quoted lines for moments where the exact wording changes the meaning of the plot.

Thematic Commentary, Rhetorical Questions, and Sales Language

Avoid stepping outside the narrative to comment on its themes. Avoid rhetorical questions aimed at the reader, since those belong to blurb writing, not to a structural document. And avoid any language that sounds like you are trying to sell the book rather than describe it. Phrases like "a gripping tale that will keep you on the edge of your seat" have no place in a synopsis; an agent already has the manuscript in front of them and does not need to be persuaded to read a document they requested.

Chapter by Chapter Summaries and Event Lists Without Motivation

Two related mistakes show up constantly in early drafts. The first is summarising chapter by chapter instead of following the story spine, which produces a document that reads like a table of contents rather than a narrative. The second is listing events without explaining why the character makes each choice, which produces a dry sequence of things happening with no sense of causality. Both mistakes make a story sound flatter and more mechanical than it actually is.

The 1 to 10 Skeleton Method

Why the Skeleton Works

If the idea of compressing a whole novel into a page feels overwhelming, the numbered skeleton method turns that abstract task into something concrete. Instead of trying to write flowing prose from a blank page, you fill in ten numbered slots, then expand each one afterward.

Step by Step: Number 1 to Number 10

Here is the method, recommended by literary agents and used across submission coaching sessions for years:

1. Write number 1: the first major event of your story, the thing that sets everything in motion.

2. Write number 10: the ending, stated in full.

3. Fill numbers 2 through 9 with the other turning points, placed in chronological order.

4. Check that every major plot point and twist has a slot somewhere in the sequence.

5. Expand each numbered point into a sentence or two of prose.

Doing steps 1 and 2 before anything else forces you to commit to your ending on the page, which removes the temptation to hedge later.

Filling the Middle with Turning Points

Once your first and last events are locked in, work through the middle by identifying the moments where the story's direction genuinely shifts: a decision made, a discovery uncovered, a relationship that changes. These are your turning points, and the skeleton method ensures none of them get lost in the process of drafting prose.

From Skeleton to Draft

With all ten slots filled, expand each into a sentence or two, then connect them with simple transitions. Keep the whole thing in third person present tense. Once you have a full draft, read it aloud. This single habit catches more awkward summary phrasing than any amount of silent rereading, and it will tell you quickly whether the piece sounds like your book or like a book report.

Annotated Synopsis Example

Full Annotated Sample

Below is a short, representative synopsis for a fictional novel called The Salt Road, followed by notes on why each part works.

MIRA VOSS has spent six years running her late father's salvage boat off the coast of a shrinking fishing town, refusing every offer to sell the business despite mounting debt. When a storm forces her to dock in a town she has avoided since childhood, she discovers the wreck of a smuggling vessel tied to her father's disappearance. Mira begins investigating, pulled between her need for answers and her fear of what those answers will cost her.

As she digs deeper, Mira uncovers evidence that her father did not die in an accident, as she was told, but was killed after threatening to expose a smuggling ring run by TOM ARCHER, the town's harbourmaster and her father's oldest friend. Mira confronts Archer, who denies everything and warns her to stop asking questions. Instead, she recruits her estranged brother to help her gather proof, risking the one relationship she has left.

The investigation escalates when Archer's crew sabotages Mira's boat, nearly drowning her. Rather than backing down, Mira uses the sabotage itself as evidence, presenting it alongside her father's old logbooks to the regional maritime authority. Archer is arrested, and the smuggling ring is dismantled. In the final scene, Mira sells the salvage boat, not out of defeat but because she no longer needs it to hold onto her father's memory. She and her brother rebuild their relationship, and Mira takes a harbour pilot position that lets her stay near the water without carrying her father's unfinished business.

Why Each Element Works

• The opening line establishes Mira's situation, her stubbornness, and the debt she is avoiding, all in a single sentence.

• The storm and the wreck function as the inciting incident, arriving early and connecting directly to her father's disappearance.

• Each paragraph advances a clear turning point: the discovery, the confrontation, the sabotage, the resolution.

• The twist, that her father was killed rather than lost in an accident, is stated plainly rather than teased.

• The ending resolves both the plot (Archer's arrest) and the character arc (Mira's choice to move forward rather than keep grieving through the boat).

Annotated Before and After Paragraph

Before: "Mira had always loved the water, ever since she was a little girl running along the docks with her father, who taught her everything about boats and told her stories about the sea that she never forgot, even years later when everything had changed and she found herself alone, running the business by herself, wondering what he would think of the choices she'd made and whether he'd be proud of the woman she'd become."

After: "Mira has run her father's salvage boat alone for six years, refusing to sell despite mounting debt."

Notes on the cut: the before version spends an entire sentence on childhood memory, emotional rumination, and unresolved questions that never connect to plot. None of it is wrong for the manuscript itself; it may well be a beautiful paragraph in context. But in a synopsis, it needs to become a single clause that states the current situation and moves on. The after version keeps only what an agent needs: her role, her history with the boat, and the financial pressure driving the plot forward.

Synopsis Types Across Formats and Genres

Novel Synopsis

A standard fiction synopsis follows everything covered so far: third person present tense, full arc, ending revealed, 500 to 1000 words. Note that this is distinct from summarising a short story for a literary magazine submission, where the compressed form of the piece itself often means a cover letter needs only a sentence or two of context rather than a full structural breakdown.

Memoir Synopsis

A memoir synopsis may be written in first person, since the story is the writer's own. The focus shifts slightly toward the personal arc and the emotional stakes of the events, rather than plot mechanics alone, but the same rule about revealing the resolution still applies.

Screenplay Synopsis

A screenplay synopsis emphasises visual storytelling and structure across acts rather than chapters. It still needs to state the ending clearly; screenwriting readers are checking for the same structural soundness as fiction agents, just through a slightly different lens focused on scene and image.

Nonfiction Proposal Synopsis

A nonfiction proposal synopsis works differently again. Rather than a narrative arc, it needs to demonstrate the book's central argument, its market position, and a rough outline of its chapters. There may not be a "twist" in the fictional sense, but the synopsis still needs to prove the book's promise holds up across its full length.

Genre Specific Emphasis

Different genres ask you to weight different elements of the story spine more heavily. Use this table as a quick reference for where to put your emphasis once the basic structure is in place.

Genre	Weight this heavily	What to reveal
Romance	Character arc and emotional stakes between the leads	The happily ever after or the emotional resolution
Thriller	Stakes, pacing, and escalating twists	The final twist and how the danger resolves
Mystery	Plot mechanics, clues, and the logic of the solution	The culprit and how the case resolves
Literary fiction	Voice, interiority, and thematic arc	The character's internal change, even if external plot is quiet

Common Mistakes to Avoid

Hiding the Ending

This is the single most common mistake, and it stems from years of training in marketing copy where the ending is the one thing you never give away. In a synopsis, withholding the resolution signals that the plot might not actually hold together, and an experienced agent will read it that way immediately.

Chapter by Chapter Summaries

A synopsis organised around chapters rather than plot points tends to include far too much detail on scenes that do not move the story forward, simply because those scenes happened to occupy their own chapter in the manuscript. Follow the story spine instead, regardless of how the manuscript itself is divided.

Dry Event Lists Without Motivation

A list of things that happen, without any sense of why the character chooses to act, reads as mechanical and forgettable. Every plot point should carry a trace of motivation: not "then she went to the harbour" but "she went to the harbour because she suspected Archer was hiding something there."

Over Editing into a Lifeless Summary

It is possible to edit a synopsis so heavily that it loses all trace of your manuscript's actual voice and becomes a flat, generic summary that could describe any book in the genre. Read it aloud periodically through the editing process and check whether it still sounds like your story specifically, not a placeholder plot description.

Ignoring Agent Guidelines

Submission requirements differ by agent, publisher, and genre, sometimes significantly. Sending the same one-size synopsis to every name on your list without checking their specific page is a preventable mistake that has nothing to do with the quality of your writing.

Mistake Audit Checklist

Run your finished draft against this list before sending:

• Is the ending hidden or hedged?

• Does the structure follow chapters instead of plot points?

• Are events listed without stated motivation?

• Has editing flattened the manuscript's actual voice?

• Have you checked this specific agent's length and format requirements?

• Has any sales language or rhetorical question slipped in?

Tools and Support for Drafting, Formatting, and Polishing

Word Processors and Page Count Control

A standard word processor with a reliable word count and page count display is enough to draft and format a synopsis. What matters more than the software itself is checking your count against the target range regularly as you draft, rather than discovering at the end that you have written three pages instead of one.

Synopsis Templates and Checklists

Building a simple template from the include and skip checklist in this guide gives you a reusable starting point for future manuscripts, rather than rebuilding your process from scratch every time you finish a new book.

Grammar and Style Checking

Running a finished draft through grammar and style checking software catches typos, tense slips, and awkward phrasing that are easy to miss after multiple rounds of cutting and compressing. This is especially useful for a synopsis, since heavy editing under a strict word count tends to introduce exactly this kind of small error, and small punctuation choices carry more weight than usual in such a short document. Even something as minor as consistent comma use in a list of plot points, a question our piece on the Oxford comma versus the serial comma walks through in detail, can make a rushed sentence read as sloppy rather than deliberate.

Agent Research and Submission Guidelines

Before finalising length and format for a specific submission, check that agent or publisher's current guidelines directly on their own listed preferences, since these details shift over time and vary widely between individual agents.

Formatting Guides and Sample Pages

A sample synopsis page with the contact block, centred title, and spacing clearly labelled is worth keeping on hand as a visual reference while you format your own, especially since a single misplaced line can make an otherwise strong synopsis look unpolished before an agent reads a word of it.

Annotated Examples and Feedback

Reading annotated examples from real, published projects teaches structure faster than reading advice alone, because you can see the reasoning behind each cut. Feedback from beta readers, a critique partner, or a professional editor before you submit is also worth the time; a synopsis benefits enormously from a second pair of eyes checking whether the story spine reads clearly to someone who has not lived inside your manuscript for the past two years. Our editing service includes exactly this kind of structural feedback on submission materials, not just the manuscript itself.

Building Trust and Authority in Your Synopsis

Cite Reputable Sources

When you are researching synopsis advice online, prioritise sources with a track record in traditional publishing and direct agent commentary over generic content farms. The advice in this guide draws on established submission conventions used across the industry, rather than a single blog's personal opinion.

Demonstrate Hands On Experience

Advice grounded in actual submission packages and real agent feedback tends to be more reliable than advice built purely from theory. If you have access to feedback from a previous submission round, even a rejection with specific notes, treat it as valuable data for your next synopsis draft.

Acknowledge When Guidelines Vary

Length and format requirements differ meaningfully by agent and genre, and any guide that claims a single fixed rule works for every submission is oversimplifying. Always confirm the specific requirements listed on each agent's or publisher's submission page before finalising your document.

Disclose Relevant Background

If you are sharing synopsis advice publicly or working with a client on their submission materials, stating your own experience with queries, synopses, and agent submissions gives readers a way to judge how much weight to put on your recommendations.

Final Checklist and Next Steps

Pre-Submission Synopsis Audit

Before you send anything, run through the include and skip checklist one more time. Confirm your length falls within the target range, your tense is consistent throughout, character names follow the capitalisation convention on first mention, and the ending is stated plainly rather than hinted at.

Tailoring to Each Agent

Keep a master version at around 750 words, then trim or expand it to match each specific agent's stated preference before sending. This takes a few extra minutes per submission and avoids the common mistake of sending an identical document to every name on your list regardless of their individual guidelines.

When to Get Feedback

Get a second read from a beta reader, a critique partner, or a professional editor before you submit. A synopsis is short enough that even one round of outside feedback can catch structural gaps that are hard to see in your own writing after so many rounds of compression.

Conclusion 

Start today with the two anchors: write number 1, write number 10, and fill the middle afterward. Expand each point into a sentence or two, then run the include and skip checklist against your draft. From there, the synopsis stops being the document you dread and becomes the one that proves your story actually works.
