After

She entered the room, trembling.

Editing process

The right pass for the page.

02

Line

Voice, rhythm, imagery, and sentence-level strength.

Copy

Grammar, consistency, and a living style sheet.

04

Proofreading

Final-pass polish before print or digital release.

THE EDIT

What arrives with the manuscript.

  1. 01

    Assessment

    A letter on structure, voice, pacing, and what to fix first.

  2. 02

    Markup

    Tracked changes at the edit level you and we agreed.

  3. 03

    Style sheet

    Names, tense, and house choices so the book stays consistent.

  4. 04

    Roadmap

    The next revision, ranked so polish never precedes story.

WHERE IT SITS

The right edit, not every edit at once.

Partnership built around authorship—clear roles, shared checkpoints, and a manuscript that still sounds like you.

Audience

Start developmental

When structure, promise, or pacing is still moving, the first pass is about the book as a whole.

Outcome

Start on the line

When the story holds, line editing, copy editing, or a proof can be the whole engagement.
