Kate Angelella – Editor

Former S&S editor w/15+ yrs experience editing NYT bestselling & award-winning authors such as Nova Ren Suma & Kekla Magoon.


I've worked as an editor for over a decade. During my time at Simon & Schuster, I acquired and edited books by award-winning and bestselling authors, including the first original novels by #1 New York Times bestselling author Nova Ren Suma; and Margaret A. Edwards Award, John Steptoe Award, Coretta Scott King Honor, and NAACP Image Award recipient Kekla Magoon.

My clients have gone on to secure publishing deals with Big 5 publishers (some at auction!), sign with agents of their dreams and managers at big Hollywood talent agencies, and author bestselling and award-winning books.

Everyone has a story to tell; I want to help you make yours the best that it can be. My critiques are thorough and honest without compromising professionalism or compassion. I want to be your coach, your cheerleader, and your sounding board to help you take your next step toward achieving your literary dreams. I especially love working with voicey books that feature badass female protagonists (the kind that wield actual weapons and the kind whose “weapons” take another form, like a sharp tongue or clever wit), swoony romance (love triangles, enemies-to-lovers, and friends-to-lovers all welcome here!), body positivity, sex positivity, and books that blur the line between reality and magic in all its many forms.

Please note: I am a thorough editor who dedicates a lot of time and attention to your story. Due to the level of detail I provide, I am not the least expensive option; if you're looking for the cheapest quote, please don't inquire.


"Any writer would be lucky to have Kate’s insightful, wise editorial guidance. In her time on the editing staff at Aladdin, Kate acquired and shaped books that launched careers of many industry stars, including the future #1 Indie Next pick author Nova Ren Suma and the multiple John Steptoe-award-winning Kekla Magoon. Kate has an eye for talent and a gentle, skilled hand at coaxing out the best from a writer."

--Liesa Abrams, Publisher, Labyrinth Road Books (Penguin Random House)

"Kate has a wonderful eye for what works in the commercial marketplace, with a talent for finding new, fresh voices and pushing them to be the best writers they can be. While at Aladdin, she shaped many noteworthy debuts, and her collaborative editorial process was appreciated and respected by her colleagues and authors. “

--Alyson Heller, Executive Editor, Aladdin Books (S&S)

“The whole thought of hiring a professional editor made me nervous, at first. But it was one of the best career decisions I have ever made. Kate’s enthusiasm for my story made me remember why I loved writing, and her spot-on edits helped me shape and hone my manuscript into something I am immensely proud of. She gave her critiques with a genuine kindness that made me feel completely at ease while also incredibly motivated. Kate’s edits gave me the push I needed, and I am so grateful.”

– Katharyn Blair, screenwriter at Marvel and author of THE BECKONING SHADOW and UNCHOSEN (HarperCollins)

I needed some open-ended creative coaching to get me out of a doom spiral and Kate was terrific! Clear, calm, totally pro about the publishing biz end of things but also really tuned in to the creative process. Highly recommend her!

So very pleased to have work with Kate! She was very professional and thorough and had so many great ideas to make my story better. Her edit letter was detailed and helped me structure the manuscript in a way I didn't think of. Our one hour zoom call was also very productive! Thank you Kate :)

Kate's feedback was incredibly helpful! She provided notes on the first 20k words of my novel to help me determine if I was going in the right direction, if my characters were well developed, and if I was starting in the right place. Her input was detailed and thorough. Highly recommend!

Kate is brilliant. She not only made my manuscript better, she gave me tools to make me a better writer going forward. I feel lucky to have found her and plan to use her on my future manuscripts. She knows what she’s doing. Don’t hesitate to choose her. No complaints. Only joy and a renewed sense of hope.

I enjoyed my experience with Kate. I was impressed with the quick responses and updates on the progress of the edit. She did an amazing job considering my manuscript was slightly larger than normal. She gave me the insights and suggestions (that I have been implementing) which I feel have elevated my story beyond what I could do alone. I especially like the follow up phone call to go over any q...
