Guide to writing your first book

How to Write a Book, Step by Step

Nine steps from a first idea to a finished book: the premise, the plan, a routine you can keep, the draft, revision, readers and publishing.

By Chandler SuppleUpdated 12 min read

To write a book, say what it's about in one sentence, choose your genre and length, and plan the chapters. Then write a complete first draft without stopping to polish it, revise it from the big picture down to the sentences, get feedback from readers, and choose between finding an agent and publishing it yourself.

Most first books take longer than people expect, and that's normal: at 500 words a day, an 80,000-word novel takes about five months to draft. Below, each step has what to do, the numbers that matter with their sources, and a free template or tool where one helps.

How to write a book in 9 steps

  1. Say what it's about

    Write your book's premise or promise in one sentence. If you can't yet, that's your first job.

  2. Pick your genre, reader and length

    Name the shelf your book belongs on and the word count readers of that shelf expect.

  3. Plan the chapters

    Sketch an outline, anywhere from a few turning points to one line per chapter.

  4. Build characters, world or research

    Know what your people want and how your world works, or gather the proof each chapter needs.

  5. Set a routine

    Pick a word target you can hit on a bad day, and a date to finish the draft.

  6. Write the whole first draft

    Keep moving forward. Leave notes for problems and fix them later.

  7. Revise from big to small

    Fix the structure first, then scenes, then sentences, then typos.

  8. Get feedback from readers

    Give the revised draft to a few readers of your genre and ask them specific questions.

  9. Choose how to publish

    Query literary agents or publish it yourself, and prepare what that path needs.

Fiction and nonfiction follow the same steps with one big difference: most nonfiction is sold before it's written. Step 2 explains when that applies to you.

Step 1: Say what your book is about in one sentence

Before you plan anything, write one sentence that holds the whole book. For a novel, that's the premise: who the story follows, what they want, what stands in the way, and what they lose if they fail. For nonfiction, it's the promise: who the book is for, and what they'll be able to do or understand by the last page.

This sentence is your compass. When you can't decide whether a scene or chapter belongs, check it against the sentence. If you have a feeling and a setting but no story yet, the plot generator gives you five complete plots in your genre to react to. Even the ones you reject tell you what you want.

ExampleA premise and a promiseWritten for this guide as teaching examples

Novel: After a flood uncovers a coffin that shouldn't be in her family's plot, a small-town funeral director has one week to learn who's inside before her brother, the county sheriff, closes the case for good.

Nonfiction: This book shows first-time managers how to run a ten-minute weekly check-in, so problems surface while they're still small instead of at the annual review.

  • Character and want. The novel sentence names one person and one goal with a deadline, which gives every chapter something to push against.
  • Stakes. Her brother closing the case is the cost of failing, and it hints at the family conflict the book will turn on.
  • Reader and result. The nonfiction sentence names exactly who it's for and the change they'll see, which is what a publisher's proposal asks for too.

Step 2: Choose your genre, reader and length

Your genre tells you what readers expect: a mystery needs a solution, a romance needs a happy ending, and a how-to book needs steps that work. It also tells you how long the book should be. Agents check word count early, and a first novel far outside its genre's range is a harder sell.

Word counts to aim for in a first novel or memoir

BookAim forGood to know
Adult novel (literary, mainstream, romance, mystery, thriller, horror)80,000–89,99970,000–109,999 is probably fine; under 70,000 or over 110,000 is likely to be judged too short or too long.
Science fiction and fantasy100,000–115,000These run long because of world-building, but very long debuts hurt your chances.
Young adult55,000–79,999The most flexible category; some agents say it can reach the 80,000s.
Middle grade20,000–55,000Simpler stories run 20,000–35,000; upper middle grade 40,000–55,000.
Memoir80,000–89,999Coming in at 70,000–79,999 is fine and shows you can focus.

Nonfiction works differently. As Jane Friedman explains, most adult nonfiction is sold with a book proposal, a business case for the book, and the publisher then pays you to write it. Memoir is the exception, since a first-time memoirist usually needs to finish the book first. Our memoir guide covers that path in detail.

Step 3: Plan the chapters

Writers plan in very different amounts. Some outline every chapter before they begin; discovery writers, also called pantsers, start with a situation and find the story as they go. Most land in between: they know the opening, a few big turns and roughly how it ends. Choose the amount of planning that keeps you writing, not the one that sounds most serious.

If this is your first book, a little structure helps more than it hurts. A three-act shape gives you a beginning that sets up the problem, a long middle where things get worse, and an ending that resolves it. Our novel outline template lays that out over 20 chapters, each with one plain job. For nonfiction, give each chapter one question your reader has, in the order they'd ask it; the nonfiction book outline template has room for each chapter's takeaway and the story or proof behind it.

ExampleOne chapter in an outlineWritten for this guide, continuing the premise from step 1

Chapter 7. Nell requests the burial permit at the county office and finds her late father's signature on it. Job: the first hard clue, and the moment she stops trusting her brother. Ends on: the clerk mentioning that someone asked for the same file yesterday.

  • One job. If you can't say what a chapter is for in a line, it may not need to exist, or it may be two chapters.
  • An ending that pulls. Planning how each chapter ends gives readers a reason to start the next one.

Step 4: Get to know your characters, world or research

Fiction runs on characters who want something. For each main character, know what they want, what they're afraid of, a belief of theirs that isn't true, and what they'd never do. Drafting will teach you more, but those four answers keep the early chapters from drifting.

Names do more work than they seem to. A name hints at a character's age, place and background, and two names that start with the same letter blur together on the page. The character name generator suggests names that fit a character's era, place and role.

Keep the facts in one place as you invent them: ages, eye colors, the layout of the town, how the magic works, who knows the secret by which chapter. A story bible, one document with the cast, places, rules and open questions for the book, saves you from rereading 200 pages to check a detail.

For nonfiction, this step is research. Gather the stories, examples, numbers and quotes each chapter needs, and write down where each one came from as you collect it, so you aren't hunting for a source the week before you send the book out.

Step 5: Set a routine and a finish date

Books get finished in small amounts done often. Choose a target you can hit on a bad day, in words or in minutes, and put your writing sessions in the calendar like appointments. Then find your finish date in the table below and write it down somewhere you'll see it.

How long it takes to draft an 80,000-word book

Words a sessionWriting every dayWriting five days a week
250320 days (about 10.5 months)64 weeks (about 15 months)
500160 days (about 5 months)32 weeks (about 7 months)
1,00080 days (about 11 weeks)16 weeks (about 4 months)
2,00040 days (about 6 weeks)8 weeks (about 2 months)

Arithmetic: 80,000 divided by your words a session. For a 60,000-word book, multiply each figure by 0.75.

Missed a day?

Don't double up tomorrow to catch up. Write your usual amount and move the finish date. A routine you keep for months beats a sprint that falls apart in week two.

Step 6: Write the whole first draft

A first draft has one job: to exist from the first page to the last. It will be uneven, and that's what drafts are for. Rereading and polishing early chapters feels like progress, but it's an easy way for a first book to stall, because a chapter can always be better and the ending never gets written.

When you hit a problem, leave a note in square brackets and keep going: a name you haven't chosen, a fact to check, a scene to come back to. Search for the brackets when you revise. You don't have to write in order, either. If the ending is vivid in your head and chapter 9 isn't, write the ending.

Dialogue is where many first drafts feel stiffest. Get the conversation down first, then fix it in revision; our guide to writing dialogue covers the punctuation, when to drop the tag, and how to make each character sound like themselves.

Stuck in the middle of a scene?

Ask what your point-of-view character wants right now and what stops them. If that doesn't move it, skip to the next scene you can see clearly. For a push, paste where you stopped into Continue My Story, read the next stretch it writes in your voice, and keep only what fits.

Keep the draft moving

  • Stop each session mid-scene, so you know exactly how to start the next one
  • Keep a running list of changes to make later instead of going back now
  • Track your word count each session; the total is the best motivation you have
  • Don't show chapters to anyone yet if their reactions would make you start over

Step 7: Rest the draft, then revise from big to small

Put the finished draft away for a few weeks before you read it. Distance lets you see what's on the page rather than what you meant. Then read it straight through, as a reader would, making notes but no fixes.

Revise in passes, biggest problems first. There's no point polishing a sentence in a chapter you'll later cut, so leave line edits and typos until the structure holds. Professional editing follows the same order, from developmental editing to proofreading; our guide to the types of editing explains each one and what it costs if you hire help.

Revision passes, in order

PassWhat you checkTypical fixes
StructureDoes the story or argument work? Are the stakes clear, and does the ending pay off the opening?Moving, merging or cutting chapters; rewriting the ending
ContinuityDo names, dates, ages and rules stay the same from start to finish?Fixing contradictions and timeline slips
ScenesDoes every scene change something? Is each told from the right point of view?Cutting scenes that repeat; sharpening how scenes open and close
LinesIs every sentence clear and in your voice?Trimming filler, varying rhythm, tightening dialogue
ProofreadingSpelling, punctuation and consistencyTypos, missing words and formatting

For a second opinion on the structure before you spend money, the AI book editor reads a chapter and writes you an editor's letter on stakes, the turn and what to cut, without rewriting a word of it.

Step 8: Get feedback from readers

Once you've revised, you need readers who don't know what you meant. Beta readers read a full draft and tell you how it felt: where they got bored, what confused them, which characters they cared about. Choose people who read your genre, and include at least one who isn't a friend or relative, since people who love you soften what they say.

If you don't have readers nearby, critique communities such as Critique Circle and Scribophile run on a trade: you critique other members' writing to earn credits or points, then spend them to post your own. Give readers specific questions rather than asking what they thought.

Questions to ask your beta readers

  • Where did you put the book down, or want to skim?
  • Was anything confusing, and did it ever clear up?
  • Which character did you care about most, and which least?
  • Did the ending feel earned? Did anything surprise you in a bad way?
  • In one sentence, what do you think the book is about?

Compare their answer with yours

If readers' one-sentence summaries don't match the premise you wrote in step 1, that gap is the most useful thing they'll tell you.

Step 9: Choose how to publish

There are two main roads. In traditional publishing, the publisher pays the costs and pays you an advance and royalties. To reach the big publishers you need a literary agent first, as Jane Friedman's guide to getting published explains, and a first novel should be finished and revised before you approach one. In self-publishing, you're the publisher: you hire the editing and cover, set the price and keep control.

Is your book ready to send out?

Before you query or publish

  • You can say what the book is about in one sentence, and your beta readers would agree
  • Every chapter has a job you can name in one line
  • The opening shows your main character wanting something, or your reader's problem
  • The ending answers the question the opening raised
  • Names, dates and rules match from the first chapter to the last
  • The word count sits in your genre's range
  • You've read the whole book at least once since your last big change
  • Your square-bracket notes are all gone

Questions authors ask

Common questions

What is the first step in writing a book?

Writing down, in one sentence, what the book is about. For a novel, that's the premise: a character, what they want, what's in the way and what's at stake. For nonfiction, it's the promise to your reader. The outline, the title and even the query letter all get easier once that sentence exists, and you can rewrite it as the book changes.

How long does it take to write a book?

Drafting an 80,000-word novel takes about five months at 500 words a day, or about 11 weeks at 1,000. To find your own number, divide your target word count by the words you can write in a session. Then add time to rest the draft, revise it and hear back from readers.

How do I start writing a book with no experience?

Start small and specific: write your one-sentence premise, a few lines on how the book begins and ends, and then the first scene you can picture. You don't need a course or special software. Read widely in the genre you want to write, write a little on a regular schedule, and expect your first draft to teach you more than any guide.

Do I need to finish my book before I look for an agent?

For a novel or a memoir, yes. Jane Friedman notes that most first-time authors must finish the manuscript before approaching agents or editors. Most adult nonfiction is the exception: you sell it with a book proposal and sample chapters, and the publisher pays you to write the rest.

Do I need to copyright my book before I share it?

No. The US Copyright Office says your work is protected the moment it's created and fixed in a tangible form, such as a saved file, and that registration is voluntary. You do need to register before you can sue over infringement of a US work, and registering puts your claim on the public record.

Can I use AI to help write my book?

Yes. How much help you take is your call, from brainstorming names to drafting scenes you then rework. If you publish on Amazon, the KDP content guidelines ask you to disclose AI-generated text, images or translations. AI-assisted work, such as editing or brainstorming for text you wrote yourself, needs no disclosure.
