The query structure: four components
A well-structured query letter has four distinct parts. First, the personalization line: a specific reason you are querying this agent. Second, the pitch: 200 to 250 words that cover your protagonist, their goal, the central conflict, and the stakes, in that order. Third, the housekeeping line: title, genre, word count, and any relevant series information. Fourth, the bio: two to three sentences about your relevant credentials. That is it. Every query that diverges significantly from this structure is harder to read and easier to pass on.
The 250-word pitch: what to include
Your pitch paragraph should introduce one protagonist, establish the story world in one or two sentences, present the central conflict, and raise the stakes. It should not introduce secondary characters, describe subplots, or explain backstory beyond what is necessary to understand the main character's motivation. Write it in present tense, active voice. The agent reading it should come away knowing who the story is about, what they want, what is in the way, and what happens if they fail. Everything else is for the manuscript.
Comp titles: how to choose and how to use them
Comp titles serve a market-positioning function. They tell an agent where your book lives in the current publishing landscape, who the reader is, and roughly what kind of advance and sales trajectory to expect. Choose books from the last three to five years. Pick titles that share your book's emotional register and target readership, not just its genre. Use a brief framing: 'for readers who loved [Title A] for its worldbuilding and [Title B] for its voice.' Two well-chosen comps are more effective than five generic ones.
The personalization line: genuine vs. generic
A genuine personalization line references something specific: a client's book you read and loved, a MSWL tweet with a specific request, an interview where the agent described exactly the kind of story you have written. It shows the agent that you did not automate your submission. Generic personalizations waste space. 'I saw you represent fantasy on your website' tells the agent nothing they do not already know. If you cannot write a genuine personalization, skip it entirely and go straight to the pitch. A strong pitch with no personalization beats a weak personalization every time.
The debut author bio: keep it short
A debut author's bio does not need to be impressive. It needs to be honest and concise. Include any prior publications, relevant writing programs, or professional expertise that directly informs the book. If you are a doctor writing medical thrillers, say so. If you have published short fiction in recognized venues, mention the most notable one. If you have no relevant credentials, two sentences acknowledging this is your debut are enough. Agents know most querying writers are unpublished. They are reading for the pitch, not the biography.
Following submission guidelines and tracking queries
Submission guidelines are not suggestions. Every agent specifies exactly what they want in a query: some want the first five pages pasted below, some want the synopsis, some want nothing but the query. Not following these guidelines is not a sign of creative independence; it is a sign that you did not read carefully. Build a tracking spreadsheet from the first query you send: agent name, date, materials sent, response deadline, and outcome. The querying process takes months and involves dozens of submissions. Track it like the professional process it is.
