What Is a Synopsis?
Quick answer: A synopsis is a one-page, present-tense summary of your novel's full plot, ending included, that agents and editors use to check the story holds together.
A synopsis is a short prose summary of your novel's entire plot, told in present tense, that reveals everything including the ending. Most agents and publishers who request one want a single page, roughly 500 to 800 words, covering the main character's arc from opening situation through the major turns to the resolution. Unlike a blurb, it does not tease; unlike a query letter, it does not sell. It demonstrates that the story works.
Writers dread synopses more than any other document, and understandably: compressing 90,000 words into 600 feels like describing a symphony by humming. But the reader of a synopsis is not looking for the book's music. They are checking structure, causality, and whether the ending lands, before they invest a weekend in the manuscript.
What a synopsis is for
An agent who likes your query and pages faces a practical question: does this book hold together for another 300 pages, and does the ending pay off the premise? The synopsis answers it in three minutes. It exposes structural problems instantly, a middle where nothing changes, a resolution by coincidence, a protagonist who never chooses anything, which is exactly why agents ask for it.
Editors use it downstream too: to brief colleagues at acquisition meetings, to check series continuity, and sometimes to commission covers and copy before reading final drafts. Contest and fellowship applications for novels-in-progress lean on synopses even harder, since the full book may not exist yet. It is a working document with a long life, worth writing well once.
The conventions, so yours looks professional
Present tense throughout, third person regardless of the novel's own narration, and character names in capitals on first appearance: MIRA, a harbour pilot with a suspended licence. Stick to one page unless guidelines say otherwise; if an agent wants three pages or five, their website will say so. No dialogue quotes, no chapter numbers, no cliffhanger withholding: the ending appears, plainly.
Limit the cast ruthlessly. Three to five named characters is usually enough; everyone else can be her brother or the rival firm. Skip subplots unless the climax is incomprehensible without them. The test for every sentence is causal weight: does this event change what the protagonist does next? If not, it belongs to the book, not the synopsis.
Writing one that does not read like a list
Bad synopses are inventories: this happens, then this happens, and then this happens. Good ones are chains: because the protagonist does this, that breaks, which forces this choice. Keep the emotional logic visible alongside the events, one clause is enough, so the reader tracks not just what occurs but what it costs. She signs the confession, trading her career for her sister's alibi, does more work than two sentences of plot.
A reliable method: write one sentence for the protagonist's situation and want, one for the inciting event, one per major turning point, two for the climax, one for the resolution. That skeleton is usually 150 words. Expand each sentence only until a stranger could follow the story, then stop. Compression is the craft here; elegance is optional.
Synopsis, blurb, logline: which is which
The three get confused constantly. A logline is one sentence, the story's engine in miniature. A blurb is marketing copy, 150 or so words that seduce a browser and hide the ending. A synopsis is the full mechanism laid on the table, ending included, written for professionals who need to see the gears. Sending a blurb when an agent asked for a synopsis reads as either confusion or evasion, and neither helps.
Length is the quickest tell. If it fits in a tweet, it is a logline. If it could sit on a back cover, it is a blurb. If it walks through the whole plot in a page, it is a synopsis. Keep all three on file for any finished novel; submissions ask for them in every combination.
Common mistakes
The fatal one: hiding the ending to preserve the surprise. Agents interpret this as the writer not trusting the ending, and they are often right. Next worst: overcrowding, ten names in the first paragraph, every subplot honoured, until no story is visible. Then there is reviewing your own book inside the synopsis, in a heartbreaking twist, in this powerful climax, which professionals read as thumbs on the scale.
Also common: synopsis voice, a flat officialese nobody would choose. You do not need to perform the novel's style, but clean, confident sentences matter, because this document is still a writing sample. And check tense discipline; drifting from present to past midway is the most frequent mechanical error in submitted synopses.
What poets can take from this
- Write in present tense, reveal the ending, and keep it to one page unless guidelines say otherwise.
- Cap named characters at five and cut subplots the climax does not need.
- Link events with because and so, not and then; causality is what the reader is checking.
- Include what key events cost the protagonist emotionally, one clause at a time.
- Keep a logline, a blurb, and a synopsis on file for every finished manuscript; submissions ask for all three.
Try it yourself
Take a novel you know thoroughly and write its one-page synopsis from memory: present tense, five named characters maximum, ending included. Then do the same for your own work-in-progress and compare which one exposes a saggy middle.
Questions
Does a short story need a synopsis?
Almost never. Magazines and contests read stories whole, so they ask for the manuscript itself, sometimes with a brief cover letter. Synopses belong to novels and novellas, where the length makes a structural summary worth having.
How long should a synopsis be?
Default to a single page, around 500 to 800 words, unless the agent or publisher specifies otherwise. Some ask for two or three pages; a few want a paragraph. Matching the stated length is part of what is being assessed.
Do you reveal the ending in a synopsis?
Yes, always. The synopsis exists so a professional can judge whether the story resolves convincingly. Withholding the ending defeats the document's purpose and signals doubt about the resolution rather than protecting it.
