Book Editing Services
Book editing gets your manuscript ready for readers. We edit for self-published authors at four levels: a developmental review, line editing, copyediting and proofreading. Editing is part of our publishing packages: proofreading from Complete, copyediting and proofreading from Premium (up to 60,000 words), and a developmental and editorial review from Rockstar (up to 80,000 words).

Developmental review
What it fixes: The big picture: structure, argument or plot, pacing, gaps and what a reader will struggle with.
Choose it when: Your draft is complete but you are not sure it works as a whole.
Included from Rockstar (up to 80,000 words)
Line editing
What it fixes: How the book reads, sentence by sentence: flow, clarity, rhythm, tone and word choice.
Choose it when: The structure is right but the prose feels flat, wordy or uneven.
Ask us for a quote
Copyediting
What it fixes: Grammar, spelling, punctuation, consistency of names and facts, and one house style throughout.
Choose it when: The book is finished and you want it correct and consistent.
Included with proofreading from Premium (up to 60,000 words)
Proofreading
What it fixes: The final check of the typeset pages: typos, missed words, and layout slips before printing.
Choose it when: Always, as the last step before your book goes to print.

What does a book editor do?
A book editor reads your manuscript the way your readers will, and removes whatever stops them: a structure that wanders, sentences that trip, inconsistent names and dates, or a typo on page 212. Good editing is invisible. Readers simply find the book easy to trust and hard to put down.
Editing happens in order, from the biggest changes to the smallest: developmental work first, then line editing if the prose needs it, then copyediting, and proofreading last, on the laid-out pages. Doing it in that order means no one polishes a chapter that is later cut.
Which edit does your manuscript need?
| If this sounds like your book | Start with |
|---|---|
| Readers say the middle drags, or the argument loses its thread | Developmental review |
| The story or argument works, but sentences feel clunky | Line editing |
| You are confident in the writing but want it correct and consistent | Copyediting |
| The book is laid out and ready to print | Proofreading |

Book editing FAQs
What does a book editor do?
A book editor reads your manuscript as your future readers will and fixes what gets in their way. Depending on the edit, that means the structure and pacing (developmental), how each sentence reads (line editing), correctness and consistency (copyediting), or the last typos on the typeset pages (proofreading).
How much does book editing cost?
We don't sell editing by the word. Editing is part of our publishing packages: proofreading from Complete, copyediting and proofreading from Premium (up to 60,000 words), and a developmental and editorial review from Rockstar (up to 80,000 words). See the packages page for each package's price.
What's the difference between copyediting, line editing and proofreading?
Line editing works on how the prose reads. Copyediting makes it correct and consistent. Proofreading is the final check of the typeset pages before printing. Most books need copyediting and proofreading; line editing helps when the writing itself needs work.
Do I need developmental editing?
Get a developmental review if you are unsure the book works as a whole: the structure, the argument or plot, or the pacing. If early readers are happy with the shape of the book, start with copyediting instead.
Can you check Scripture references in a Christian book?
Yes. We can check the Bible verse references in your manuscript as part of editing, so each quotation matches the passage it cites.
How long does it take?
A full publishing package takes 4–6 weeks standard; occasionally up to 8 weeks.
Do I keep the rights to my book?
Yes. You keep 100% of your rights and royalties.
