Line editing differs from a full manuscript review in that in addition to an editorial letter, you also receive your manuscript with detailed edits and comments. The line edit includes top-line comments and suggestions (plot, pacing, characters) as well as more specific feedback line-by-line, on dialogue, style, balance of scene and summary, grammatical mistakes, etc. This includes a half-hour Zoom consultation at the end to discuss the edit.
My rate is $.06 a word. For an 80,000 word manuscript, that would be around $4,800.
Manuscripts that involve fact-checking or include bibliographies incur an additional charge.
