Kaitlyn Katsoupis – Editor

Literary Agent offering manuscript critiques, developmental edits, and submission polishing for fiction novels readying for publication

Overview

I am a freelance editor and literary agent with nearly a decade of experience in the book publishing industry. With a degree from Emerson College in Writing, Literature, & Publishing, I have extensive knowledge in the tools needed for polishing and readying a fiction novel for either submission to an agent/editor, or for readying it to be released in the self-publishing world.


I offer editorial services that focus on feedback/guidance for full manuscripts as well as getting your first pages and supplemental info sparkling before you send them off to an agent. My focus is to provide a Compliment Sandwich critique technique: highlight your strengths and hooks, but also provide guidance and suggestions for areas that need revision or fine-tuning. Often, my turnaround time for full manuscripts in 2-4 weeks, depending on word count and level of edit needed.

Kaitlyn was great! She provided developmental editing services for me, and I am impressed by her remarkable ability to provide constructive criticism that significantly helped my understanding of the way forward. She has a keen eye for both the overarching narrative and the finer details of my writing. I wholeheartedly recommend Kaitlyn to any writer seeking a dedicated and insightful editor.

Kaitlyn helped me make the decision between going with traditional publishing vs. self-publishing for my series of fantasy novels.
