Historical Nonfiction Book Copy Editor

I'm seeking an experienced copy editor for my historical nonfiction book. The ideal candidate should have:

- A strong background in editing historical nonfiction.
- Proficiency in copy editing with a keen eye for detail.
- Excellent command of the English language and grammar.
- Ability to maintain the author's voice while improving the text's clarity and flow.

Experience with the Chicago Manual of Style is preferred, but not mandatory. The main goal is to enhance the manuscript's readability and polish.
