Alethea Spiridon – Editor

Partnering with authors for 25+ years, I bring expert editing in all genres. Let's shape your story and achieve your goals together!

Overview

Looking for an editor who will strengthen your manuscript without losing your voice? That’s my specialty. With 20+ years in publishing, I bring honesty, clarity, and collaboration to every project, guiding your work to its best possible form.

My career began at Harlequin Books, where I spent seven years acquiring and editing women’s fiction. For 14 years, I was a senior editor (and former editorial director) at Entangled Publishing, where I worked with authors across genres, including voices that went on to hit the New York Times bestseller list.

From developmental edits and manuscript evaluations to fine-tuning style and structure, I’ve helped hundreds of writers — debut and established — find confidence and clarity. Whether you’re writing fiction, nonfiction, or even a screenplay, I’ll meet you where you are and help bring your vision to life.
