My first book proposal was 47 pages. I spent six months on it. It had charts. It had market analysis. It had a detailed chapter outline.
Twelve agents rejected it. Two didn't respond at all.
The proposal that finally got me signed was 12 pages.
Here's what I learned about book proposals—and why most of them fail before an agent even finishes reading.
The First Page Problem
Agents receive hundreds of proposals. Most get rejected on the first page.
Not because they're bad. Because they start wrong.
Most proposals open with "I'm writing to propose a book about..." or dive straight into market analysis. This is backwards.
The first page needs to answer one question: Why will anyone care?
Start with the hook. The urgent problem. The surprising insight. The story that makes them lean in. Market analysis can come later—first, make them want to keep reading.
The "So What?" Test
Every sentence in your proposal should survive the "so what?" test.
"I've been a professional writer for 15 years." So what?
"My blog has 50,000 monthly readers." So what?
"This book will help people communicate better." So what—there are hundreds of those.
Now try: "After coaching 200 executives through their worst communication failures, I identified three patterns that predict whether a crisis becomes a career-ender or a growth opportunity. This book teaches readers to recognize and avoid them."
That survives the test. There's a specific insight, specific expertise, and specific value proposition.
The Title Matters More Than You Think
Your title isn't just a name—it's a pitch.
Weak: "Better Communication in Business" Strong: "The First Sixty Minutes: How to Communicate Through Any Crisis"
The strong title promises something specific. It suggests a framework. It makes you curious.
Spend real time on your title. It appears in every email, every meeting, every pitch. Make it work hard.
The Platform Question
Agents care about platform—your ability to reach readers.
But "platform" doesn't mean you need a million followers. It means you need evidence that people want what you're offering.
Strong platform signals:
- Newsletter with engaged subscribers
- Podcast appearances on relevant shows
- Speaking engagements
- Previously published articles on the topic
- Professional credentials that matter for this topic
- Community you're embedded in
Weak platform signals:
- Instagram followers (unless the book is visual)
- Generic "social media presence"
- Credentials unrelated to the book topic
One focused newsletter with 5,000 engaged subscribers is worth more than 50,000 random Twitter followers.
The Competitive Analysis Trap
Every proposal needs competitive analysis. Most do it wrong.
Wrong approach: List 10 books in your space, then explain why yours is better than all of them.
Better approach: Show you understand the category, identify the gap, and explain how your book fills it.
"Atomic Habits dominated the behavior change space with a focus on tiny changes. Essentialism taught people to do less. My book addresses the gap between them: how to decide which habits are worth building in the first place."
This isn't saying other books are bad. It's showing where you fit.
The Chapter Outline
Your chapter outline has two jobs: show the book's structure and prove you can fill 200+ pages.
Each chapter summary should:
- Have a clear, interesting title
- Explain the main concept in 2-3 sentences
- Include one specific story or example you'll use
- Show how it connects to adjacent chapters
This isn't the actual book. It's evidence you've thought through the book.
Sample Chapters
Most proposals include 1-3 sample chapters. These should be your best work—not necessarily Chapter 1.
Pick chapters that:
- Showcase your voice
- Include your best stories
- Stand alone (don't require reading everything before them)
- Demonstrate what makes your approach unique
Polish these until they're publication-ready. This is the agent's only glimpse of your actual writing.
The Query Letter
Your query letter is the cover page of your proposal. It's often read separately—sometimes it's all that's read.
Structure:
- Hook (1-2 sentences that make them want more)
- What the book is (1 paragraph)
- Why you're the person to write it (1 paragraph)
- Relevant credentials and platform (1 paragraph)
- Closing (express enthusiasm, mention what's attached)
Total length: One page. Maybe 300 words.
This is harder than writing 47 pages. Every word has to earn its place.
The Follow-Up Reality
Most proposals get rejected. Even good ones.
An agent might:
- Not represent your category
- Have similar books already
- Be too full to take new clients
- Simply not connect with your voice
Rejection doesn't mean your book is bad. It means this particular agent wasn't the right fit.
Keep querying. Most successful authors collected dozens of rejections first.
What Finally Worked
The proposal that got me signed did a few things differently:
- Opened with a story, not credentials
- Made a specific promise in the first paragraph
- Showed platform through results (not just follower counts)
- Kept everything ruthlessly short
- Included the best sample chapter, not the first chapter
And honestly: it found the right agent at the right time. Timing matters more than anyone admits.
The Real Point
A book proposal isn't really about the book. It's about convincing someone to bet on you—your ideas, your voice, your ability to deliver.
Write it like you're making a case, not filing paperwork.
