James Mustelier – Editor

Developmental editor with wide ranging experience in genres from middle grade to adult, including books by NY Times best sellers.

Overview

I'm an editor, writer and literary agent with an MFA in creative writing, and experience as the in-house editorial consultant at a leading literary agency. As an editorial consultant, I've worked on developmental edits across a wide array of genres, including books by NY Times best selling authors. From middle grade sci-fi, to young adult fantasy, to adult literary fiction, I have the editorial experience and market knowledge to shape and steer manuscripts to their most fully realized and marketable form. I tailor my editorial approach to each writer I work with, and prioritize clear communication and maintaining the author's vision for their project throughout the editorial process.
