A synopsis isn't a summary. It's a compressed version of your story's spine. Here's how to write one that works.
Start Writing Better →Agents read synopses for one reason: to evaluate structure. They want to know whether the story you've promised in the query holds together from beginning to end. Does the inciting incident lead logically to the central conflict? Does the protagonist's arc complete? Does the climax arise from the story's established logic rather than coincidence? Does the ending deliver the emotional payoff the opening set up? A synopsis that reveals structural problems is doing its job, even if that job is unpleasant for the writer. Many manuscripts get rejected at synopsis stage not because the premise is weak but because the structure doesn't hold. If you find the synopsis hard to write, take it seriously as a diagnostic. The difficulty is almost always telling you something true about the manuscript.
Always read submission guidelines first. When an agent specifies a length, follow it exactly. When no length is given, default to one page single-spaced (approximately 500 words). The one-page synopsis is the industry standard for initial queries. Some agents request a longer synopsis after reading sample pages: this is a positive sign and usually means they want to evaluate whether the full story delivers. For a longer synopsis (two to three pages), you have room to include one or two significant subplots, more character development, and more detail about the climax and resolution. Format: standard manuscript format, agent's name and book title in the header, single-spaced, one-inch margins. Title the document “[Your Name] – [Title] – Synopsis” so agents can identify it easily in their submission management systems.
The most effective synopsis openings establish two things in the first two sentences: what the protagonist wants (their external goal) and what they need (their internal wound or the thing standing between them and genuine change). These are not always the same thing, and the gap between them is often where the story's real meaning lives. A protagonist who wants to defeat the villain but needs to forgive their father before they can is more interesting than one who simply wants to win. Open your synopsis by naming your protagonist, their world, their want, and their need. This grounds the agent in character before plot. Agents trust writers who demonstrate that they understand the difference between what a character pursues and what they require. That understanding is the foundation of a story that means something.
The ending must be in the synopsis. There is no negotiation on this. Agents use the synopsis to determine whether the book is structurally complete, and a synopsis without an ending is structurally incomplete by definition. Write the ending clearly and specifically. Name who survives, who changes, what is resolved, what is lost. Be concrete: “Elena destroys the artifact but loses her brother in the process, and the kingdom is freed but at a cost she will carry forward” is a real ending. “Elena must make the ultimate sacrifice” is not. If you feel that revealing the ending undermines the book, you may be confusing a synopsis with a jacket blurb. The jacket blurb teases. The synopsis spoils. That is its function. Embrace it.
A synopsis written in flat, bureaucratic prose wastes an opportunity. The synopsis is a writing sample as much as the query letter and the pages. An agent reading a tight, propulsive, well-voiced synopsis will feel more confident about the manuscript than one reading a lifeless plot summary. This does not mean the synopsis should be lyrical or experimental. It should be clear, direct, and written in the same emotional register as the book. A dark thriller synopsis should feel tense. A witty romantic comedy synopsis should have lightness to it. The character's emotional experience should be present even in compressed form. Avoid passive constructions. Prefer active verbs. Let the protagonist's personality come through in how you describe their choices. Voice in a synopsis is the difference between “a decision is made” and “she burns the letter.”
The most fixable synopsis failures: too many characters, too many subplots, and no ending. Too many characters: name only characters who directly affect the main plot. Every named character costs the reader cognitive load. Use a pronoun for minor characters instead of a name. Too many subplots: the synopsis covers the main arc only, with one or two supporting threads if they directly affect the protagonist's central journey. Cut everything else. No ending: as covered above, the ending belongs in the synopsis without exception. Additional failures: writing in past tense instead of present; writing in first person instead of third; describing themes instead of events (“the novel explores identity” instead of showing what actually happens); and losing cause-and-effect logic between scenes. Each major event in the synopsis should follow from the previous one. If it doesn't, that is a structural problem in the manuscript, not just the synopsis.

Get Started Free →Always follow the requesting agent's specific guidelines first. When no length is specified, a one-page synopsis (approximately 500 words, single-spaced) is the safest default for query submissions. Some agents request a longer synopsis, typically two to three pages, particularly for complex plots or series fiction. When in doubt, shorter is better. A tight one-page synopsis that covers every major plot point and the ending is more impressive than a sprawling three-page document that loses the thread. Treat the length constraint as a craft challenge: if you can't compress your story's spine into 500 words, you may not fully understand your story's structure yet. The compression process itself is diagnostic. Where you struggle to summarize is often where your structure has problems.
Yes. A synopsis that ends with “to find out what happens, read the book” or any variation of a mystery ending is a red flag for agents. The synopsis exists specifically so agents can evaluate your story's complete structure, including whether the ending delivers on the promise of the opening. Agents need to know that you can land the plane. A great premise with an unsatisfying resolution is still an unpublishable book. Your ending must be in the synopsis. If you are worried that the ending will be judged harshly, that is valuable information: it means the ending may need revision before you query. The synopsis is also useful as a self-diagnostic tool for this reason. Writing it forces you to confront whether your structure holds all the way to the final page.
Write your synopsis in third person, present tense, regardless of your book's point of view or tense. This is publishing industry convention, and departing from it flags inexperience. Third person present creates immediacy and universality: “Elena discovers the letter and understands what it means” rather than “I discovered the letter” or “Elena discovered the letter.” The exception is if the agent specifically requests a different format. Some agents prefer first-person for first-person novels. Always follow specific submission guidelines over general conventions. If no instructions are given, third person present is the safe default that no agent will penalize you for.
In a synopsis, follow the dominant storyline and only introduce additional POV characters when they are directly relevant to the main plot. The synopsis is not a chapter-by-chapter summary. It is the story's spine. If your book has four POV characters, the synopsis should make clear whose arc drives the central conflict, and mention the others only in the context of how they affect that central arc. When you first introduce each named character, capitalize their name in full to help the agent track who is who. Keep the character count in your synopsis low. If the agent encounters eight new names in 500 words, they will lose track. Prioritize ruthlessly. Subplot characters who don't affect the main arc do not belong in the synopsis.
The most common synopsis mistakes: including too many subplots and secondary characters, which obscures the main story; withholding the ending; using vague emotional language (“she must confront her past”) instead of concrete plot events (“she finds the evidence that implicates her father”); losing the protagonist's emotional journey in favour of plot mechanics; writing in a different tense or person than the convention; and failing to show the cause-and-effect logic that links each major event to the next. A synopsis should read like a lean, compelling version of the story, not like a plot list. Each sentence should follow logically from the last. The agent should finish reading it knowing exactly what the book is, why it matters, and whether the ending works.
