Done right, it can open doors to publishing deals and literary representation.
In this guide, you’ll learn exactly how to write a professional, compelling book cover letter in 2025, whether you’re a first-time author or a seasoned writer looking to polish your submission. Let’s start with the basics.

ToggleWhat Is a Book Cover Letter?
A book cover letter is a brief, professional letter that authors send alongside their manuscript, book proposal, or sample chapters when submitting to literary agents, publishers, or editors. It introduces your book and provides important context — who you are, what your book is about, and why you’re contacting that particular person or publishing house.
In short, it’s your personalized sales pitch. It helps the agent or editor decide whether to read your manuscript or move on to the next query.
A strong book cover letter typically includes:
- The title, genre, and word count of your book
- A concise book summary or hook
- Your author bio or writing background
- A personalized note explaining why you’re submitting to that agent or publisher
- A clear and polite closing statement
Even in today’s digital publishing world, this letter continues to play a vital role in the traditional submission process. A well-written cover letter can make your book stand out in a crowded inbox.
Step-by-Step Guide: How to Write a Book Cover Letter
Now that you understand what a book cover letter is, let’s break down the writing process into clear, manageable steps.
Step 1: Open with a Clear Introduction
Begin your letter with a simple, confident opening. This is where you mention your book’s title, genre, word count, and who it’s written for. Keep it professional but engaging.
Example:
I’m seeking representation for my completed 95,000-word psychological thriller, Beneath the Fog, which will appeal to fans of The Silent Patient and Sharp Objects.
This demonstrates that you understand your audience and provides the agent with a concise overview of your book’s key elements.
Step 2: Include a Short, Powerful Book Summary
Think of this section like the back cover of your book — just a few compelling sentences that make someone want to keep reading. Don’t try to include every detail; just give a taste of the story, the main conflict, and the stakes.
Tips for writing your summary:
- Focus on the main character, their goal, and what’s at risk
- Keep it between 3 to 5 sentences
- Avoid vague language — be specific and vivid
Example:
When a forensic psychologist is called to evaluate a teenager accused of a brutal crime, she uncovers chilling connections to her long-buried trauma. As the investigation deepens, she must confront her past or risk losing everything — including her sanity.
Step 3: Introduce Yourself as the Author
Now it’s time to briefly share your background. Mention any relevant writing experience, publications, awards, degrees, or involvement in the writing community. If you’re a debut author, that’s perfectly fine — focus on your writing journey or any work that relates to your genre.
What you can include:
- Publishing credits (magazines, anthologies, contests)
- Writing education (MFA programs, courses, workshops)
- Professional or personal experience related to your book’s topic
- An online platform or blog (if relevant)
Example:
I have a BA in Psychology and have worked with at-risk teens for over a decade — experience that heavily influenced this novel. My short fiction has appeared in Writers Weekly and Fiction Front, and I was a finalist in the 2024 Reedsy Short Story Contest.
Step 4: Personalize the Submission
Never send a generic letter. Always tailor your letter to the specific agent or publisher you’re contacting. This shows that you’ve done your research and respect their work.
How to personalize:
- Mention a book they represented or published that you admire
- Refer to their website, bio, interview, or manuscript wish list (MSWL)
- Align your book with the genres or topics they’re interested in
Example:
I’m reaching out to you because of your interest in suspenseful fiction with strong female protagonists. I particularly enjoyed your client Kelly Marks’ Cold River, which shares similar psychological themes to my manuscript.
Step 5: Close Professionally
End your letter with a clear and polite conclusion. Thank them for their time and mention what you’ve attached or included based on their submission guidelines (e.g., sample chapters, synopsis).
Example:
Thank you for considering my submission. I’ve included the first three chapters and a brief synopsis as per your guidelines. The full manuscript is available upon request, and I’d be delighted to share it with you.
Then, simply sign off with:
Sincerely,
Your Full Name
What to Avoid in a Book Cover Letter?
Even a strong manuscript can be held back by a weak or unprofessional cover letter. Here are some common pitfalls to avoid:
- Making it too long or overly detailed
- Using a casual or overly emotional tone
- Comparing your book to bestsellers with unrealistic claims
- Forgetting to include the book’s genre, title, or word count
- Sending the same letter to multiple people without personalization
- Including your entire life story or every plot twist
Tips to Make Your Book Cover Letter Stand Out
In 2025, the publishing world will be faster and more competitive than ever. Use these tips to stand out:
- Keep it short — one page only
- Use clear, professional language
- Focus on your story’s hook, not just your background
- Show you’ve researched the agent or publisher
- Follow submission guidelines exactly (format, attachments, etc.)
- Always proofread before sending — no spelling or grammar mistakes
