Cassidy Sachs – Editor

An editor at a Big 5 publisher with experience editing NYT bestsellers, specializing in adult commercial fiction and narrative nonfiction.

Overview

Hi! I'm an editor with over eight years industry experience. I specialize in adult commercial fiction, particularly in the genres of contemporary, book club, romantic comedy, and women's fiction, as well as adult narrative nonfiction across a broad array of genres including history, politics, and journalism.


I view editing as an exercise in empathy, and love working closely with authors to shape the best possible version of their book to make sure the story they want to tell, the message they hope to deliver, and the empowering perspective they want to share, come through clearly.


I am available to provide structural editorial notes to help at the development stage, a closer line-edit for projects that are further along and specialize in long form editorial letters that assess your project's strengths and weaknesses and help you plan for the best path forward. I also provide proofreading services for manuscripts that are in need of a final polish.


I am a thorough and thoughtful editor, eager to bring my expertise to your work!

Cassidy is one of the most positive and kind people I’ve ever had the pleasure of working with, and I’m truly sad our collaboration is finished. Her real-world insights from her experience with current traditional publishing trends helped point out areas in my story structure that would not seem optimal to an agent or publisher, with suggestions on how to fix them. Anyone would be lucky to work...

With Cassidy’s encouragement, I submitted my manuscript to an agent who signed me upon reading it. I am so thankful to have had the opportunity to work with her. She is an asset to this industry. Highly recommend.
