Amanda Sumner – Editor

Former NY publishing house editor with 30 years of experience. I help authors create books that are even better than they dreamed.

Overview

Hi, author! I'm excited to meet you.

I'll let a few of my clients tell you why you might be excited to meet me:

“Amanda has been my go-to freelance editor for years. She is thorough and thoughtful, and I trust her work implicitly. In fact, she is so good that readers have left comments on how well-edited my book is. Seriously. More importantly, she is a lovely person and a dream to work with. I recommend her highly!!”

— Natalie Charles, Daphne du Maurier Award finalist, Romantic Times Reviewers’ Choice Award winner

“I’m so glad I found you. Your insights and guidance have definitely made me produce stronger work.”

— Alison Ragsdale, two-time Independent Publisher Book Awards (IPPY) medalist

“I could not ask for a more understanding, funny, compassionate, and hard-working editor. For real. You keep me sane and even-keeled when I want to chuck it all in, you talk me down off the ledge when I think I’m utter rubbish, and your enthusiasm for my work makes me want to be a better writer. Please don’t ever leave me.”

— Shawnee Small, two-time USA Today bestselling author

While I love these compliments, nothing gives me more satisfaction than seeing an author’s manuscript start to shine as we work together to shape it into the best book possible. I consider myself a partner to my clients. I scrutinize every word, sentence, and paragraph to make sure it's as strong as it can be—while remaining true to the author’s voice and vision.

My editing career started in 1992 at a small literary press (now part of HarperCollins). I later worked at W. W. Norton, and I edited for Prentice-Hall for years. For over 15 years, I was a member of Romance Writers of America (RWA), and I twice gave workshops (one on editing software and one on writing about sex) at RWA national conferences.

My favorite genres are romance, thriller, paranormal, erotica, women’s fiction, and literary fiction, but I love trying new genres and editing cross-genre projects. I have edited a considerable number of YA novels and a few middle-grade books.

Please get in touch and tell me about your book!

This particular book was a difficult one to copy-edit. Changing it from Australian English to American was the first challenge, which Amanda tackled easily. Getting the vernacular specific to the period and setting correct was the second, which resulted in a lot of back-and-forth between us while...
