How to Write a Novel Synopsis: The One-Page Method, With an Example
A novel synopsis tells the whole story, ending included, in the present tense, on one page: one paragraph per act, each centred on what the main character wants, what they do and what it costs them. It is not a teaser, it is not an analysis, it is the bare narrative, the way an agent or an editor needs to read it to know whether the structure holds before opening the manuscript. Here is the method in four paragraphs, a complete synopsis of a fictional novel, and the fastest way to produce one: starting from the chapter summaries in your outline.
What a synopsis is, and what it is not
Three short texts travel with a novel, and they get confused.
| Text | Length | Reveals the ending? | Who it is for |
|---|---|---|---|
| The pitch | Fifty words | No | The query letter |
| The blurb | 100 to 150 words | No | The reader in the bookshop |
| The synopsis | One page (two at most) | Yes | The agent, the editor |
The synopsis reveals the ending. It is the point writers resist most, and it is not up for debate: the agent wants to know whether you can finish a story, and the reader at the house has no time to read 80,000 words to find out. The pitch keeps the secret; it is worked out in how to write a query letter that gets read. The blurb has its own structure, described in how to write a book blurb.
The method: one paragraph per act
Four paragraphs, present tense, third person, no dialogue, no quality adjectives ("heartbreaking", "gripping") and no opinion on your own book.
Paragraph 1, the situation and the disruption. Who the character is, where, what they want, and the event that breaks the routine. Name the two or three characters who matter, in capitals or bold at first appearance, never more than five names in the whole synopsis.
Paragraph 2, the rise. What the character tries, what fails, what they learn. A synopsis does not list scenes; it chains causes: "because", "so", "but".
Paragraph 3, the turning point. The revelation or the loss that changes the novel's question. Often the middle of the book.
Paragraph 4, the resolution. The final choice, its price, and the character's state on the last page. Write the ending in plain words.
Length: between 400 and 600 words for a standard-length novel. If an agent asks for two pages, you expand paragraph 2; if they ask for half a page, you cut paragraph 2.
A complete synopsis
Fictional novel: "The Silence of the Bogs", rural crime, 82,000 words.
Nadia Ferrand, thirty-nine, a police officer, is transferred to Saint-Aubin-des-Tourbières, the village she left at fifteen when her mother disappeared without leaving an address. In her first week, a peat worker finds a woman's shoe in a layer of peat dated to the 1990s. Nadia recognises the shoe.
She asks to reopen her mother's file; her superior, Captain Morel, refuses: voluntary disappearance, case closed. Nadia investigates alone, in the evenings. She learns that her mother worked for Joseph Kerhervé, owner of the peat bog, and had filed a complaint against him two months before vanishing. The complaint is no longer in the archives. Nadia confronts Kerhervé, who receives her with a friendliness that chills her, then discovers that Morel was the officer who took the complaint, and buried it.
When Nadia obtains the excavation of the peat layer, no body is found, but a suitcase: the one her mother packed the night she disappeared. Nadia understands that her mother really did leave, and was caught. Morel, cornered, admits covering for Kerhervé over a gambling debt, but swears he knew nothing of what followed. Kerhervé says nothing.
Nadia finds the only person who saw her mother that night: her own father, who always told her she was asleep when her mother left. He admits he let her go, saw her get into Kerhervé's car, and kept silent for twenty-four years for fear of losing the farm. Nadia has Kerhervé arrested for murder on the strength of that testimony and a DNA trace in the suitcase. She does not forgive her father. She stays in the village, because it is the only place where she knows who she is.
Four paragraphs, five names, the ending in plain words, about 380 words. Nothing about style, nothing about themes. An editor knows within two minutes that the plot closes, that the reversal sits in the right place, and that the ending does not cheat.
Starting from the chapter summaries in your outline
The shortest way to write a synopsis is not to draft it cold, it is to condense. If your outline holds a summary per chapter, you already have the material. Here are the summaries of chapters 1 to 4 of the fictional novel:
- Nadia arrives in Saint-Aubin, moves into the staff house. Memory of the night her mother left.
- The shoe is found at the bog. Nadia recognises it, says nothing.
- Nadia asks for the file to be reopened. Morel refuses.
- First evening of solo investigation: the archives, the missing complaint.
Four chapters, four lines, and the first paragraph of the synopsis is half written: remove what has no consequence (the staff house, the memory) and keep the causes. In the Sagoræ studio, the outline in the novel hub keeps one summary per chapter; you export them in one block, then cut. Dédale helps you cut: summary by summary, it asks "what changes if this chapter leaves the synopsis?". If the answer is "nothing", it goes. Dédale does not write the synopsis; it makes you find the spine. A complete outline, chapter by chapter, is shown in a novel outline example, filled in.
D Daedalus · Story architect Pre-recorded demo
Daedalus stress-tests the outline of "What the Sea Gives Back"
Daedalus
Your feeling is right, and the outline shows why. From chapter 9 to chapter 22, Maud looks for a buyer. Looking is not an event: it is a state. Nothing stops her from looking for thirteen chapters.
Three questions, and no answers on your behalf:
- Where is the midpoint? Something around chapter 14 has to make going back impossible. A buyer who signs, then pulls out? A discovery about the father?
- What does Jonas want? He appears in Act II with no goal of his own. A character who wants nothing does not create conflict, he creates a pause.
- Why does the cannery burn? If it is an accident, the climax comes from outside. If it is the consequence of a choice Maud makes in Act II, the whole middle tightens at once.
Daedalus
Then your Act II has just found its spine: Maud needs the money of the man who wants to destroy what she is trying to save. Your midpoint almost writes itself (she signs, or refuses to sign), and the fire in chapter 23 changes meaning depending on who holds the match.
I am not updating anything: it is your outline. Add the line "Jonas = buyer" to chapters 9 to 16 and look at what each chapter now has to contain.
Pre-recorded simulation. Daedalus never writes: it questions the structure of the novel and leaves the decisions to the author.
The mistakes that show immediately
- Opening with the setting or the era instead of the character.
- More than five names: the reader loses the thread.
- Sentences of judgement: "in a devastating finale". Tell the finale.
- Past tense: a synopsis is written in the present.
- The hidden ending. Non-negotiable.
- Two pages when the agent asked for one.
Once the synopsis is ready, it joins the query and the pages in the submission package, whose full route is described in how to get published in 2026.
Frequently asked questions
How long should a novel synopsis be? One page, 400 to 600 words, unless the agent or house says otherwise. Some ask for two pages: you then expand the rise, never the ending.
Should a synopsis reveal the ending? Yes, always. The synopsis exists to check that the story is built through to the end; hiding the ending is the same as not sending one.
What is the difference between a synopsis and a blurb? The blurb makes the reader want the book and stops before the ending; the synopsis tells everything, in the present tense, for a professional.
What tense should a synopsis be in? Present tense, third person, even if the novel is in the past tense or in first person.
