Overview

I've spent more than twenty years as a commercial fiction and non-fiction editor in Big5 Publishers including Macmillan, Penguin Random House, and HarperCollins, including running Harper Voyager, the science fiction/fantasy imprint at HarperCollins for twelve years. Best-selling and award-winning authors I've worked with include Charlaine Harris, Kim Harrison, Susan Dennard, Richard Kadrey, Mark Lawrence, Zen Cho, Katie McGarry, Eric van Lustbader, and more.

I specialize in commercial fiction of all genres for both adult and young adult, particularly science fiction and fantasy, but also thrillers, romance and supernatural/horror. I do select narrative non-fiction as well. I'm known for my editorial skills as a story editor in particular. I also offer publishing/marketing consulting--need to improve your social media profile or marketing plan, build a compelling query and pitch? I can help.

Having Diana's deep experience applied to my query letter, synopsis, and first 10 pages was an essential wake-up for me, sure to strengthen the appeal of my novel. Her suggestions on what to avoid and what to emphasize were spot on. She responded promptly when I had questions, and she returned her full suite of comments and a detailed line edit several days earlier than I expected.

Peter--I'm so glad I could be of help! Thank you. Best wishes on your continued writing journey!

I could not be more happy with the editing work of Diana. Among strengthening the story line and cleaning up grammar, she also fixed all my present/past tense issues and resolved some POV issues. A true professional and I was very lucky to have found her. The book is so much stronger. She gets my highest recommendation.

Reply from Diana G.

Thank you! It's been great wokring with you as well!
