Jeanine Le Ny – Editor

Best-selling book developer, dedicated talent nurturer, and enthusiastic editor of fiction and nonfiction for ages 0 to teen.


Hi! I’m a dedicated editor, specializing in fiction and nonfiction for kids ages 0 to teen, and it would be my honor to help you bring your work to the next level. I have over 20 years of experience nurturing talent and editing best-selling books for the major publishers. I’ve also written and ghostwritten for Scholastic, HarperCollins, and Penguin Random House, but my true calling is as an editor, idea developer, and author cheerleader.


I’ve coached countless writers—both new and well-established—on everything from world-building and plot development to characterization, tone, and beyond. You name it, we’ve worked on it: picture books, middle grade, YA, graphic novels, family and friendship stories, romantic comedies, coming-of-age, thrillers, mysteries, supernatural, dystopian, horror. . . . Can you tell I love a good genre?

Some of my more familiar work includes NANCY DREW and HARDY BOYS mysteries as well as an early reader series I co-created called Nancy Drew Notebooks. I worked closely with R.L. STINE, editing the iconic FEAR STREET and many of his single titles, and I was the brain behind a multitude of MARY-KATE AND ASHLEY OLSEN books (over 40,000,000 sold). I was also an original editor of Thomas Kinkade’s CAPE LIGHT, a popular line of Christian-themed novels for adults.


I’ve launched the writing careers of dozens of subject matter experts—educators, scientists, therapists, among others—who had always wanted to publish but needed the right editor to help them realize their dream.

My nonfiction list is comprised of best-selling picture books, such as THE BACKYARD BUG BOOK FOR KIDS by Lauren Davidson, and a host of beautiful narrative and instructional titles, biographies, photographic and illustrated reference, STEM activity books, craft books, cookbooks, health and wellness workbooks, as well as other purposeful books that develop skills and enrich the minds of kids, teens, and their parents.

I also established a collection of educational workbooks that have sold over 3.8 million copies, including the MY WORKBOOK series for grades Pre-K to 2, and MY FIRST LEARN-TO-WRITE WORKBOOK, which was the #1 nonfiction book in America for 12 weeks in 2020 and still ranks #1 in Education Workbooks on Amazon.


Whether your passion is fiction or nonfiction, we’ll work to bring your book to its fullest potential, and I’ll meet you wherever you are in your process. Together we’ll celebrate your wins and, wherever you need help, I’ll draw on my expertise to give you constructive feedback that’s compassionate, honest, and actionable so that you can improve your book and grow as a writer, too. I'll also offer ideas and solutions, and maybe even a funny drawing here and there to spark your creativity.

It's my goal, as your editor, to help you find your voice and your audience, to help you tell your story, and to honor your artistic vision throughout the entire journey. Contact me today. I can’t wait to hear what you’re working on!

Work experience

Callisto Media

Sep, 2018 — Jul, 2022 (almost 4 years)

At Callisto, I began as a Senior Editor where I used data and consumer insights to develop, outline, and edit nonfiction books from the initial idea to the final manuscript. I worked closely with subject matter experts and influencers, who were also first-time authors, coaching and guiding them to write the company's top performing books. Later, I was promoted to a new role where I focused on creating the vision and strategy for over 250 nonfiction titles per year in the Kids, Teens, and Education categories. I conceived everything from position and value proposition to specs, budget and revenue forecasts, and I made sure that each stage of the production process remained true to my initial vision.
