It's been such a pleasure to have the opportunity to work with Kate! She's very professional, organized, creative and a brilliant writer. We needed some help to bring our young adult fantasy-fiction novel to life and Kate really nailed it for us. I hope to get the opportunity to work with her again.

Kate was amazing to work with! My writing and story benefited greatly from working with Kate. Detail orientated and knowledgeable about the craft, Kate helped me take my manuscript to a level that I could not achieve on my own. I 100% recommend working with Kate and cannot put into words how great of a job well done she did.

Kate's edits have been informative and valuable. Her feedback and the editorial letter were exactly what I was looking for and have given me a good direction to continue improving my story and writing. Her work exceeds expectations, when I needed additional time to deal with a personal tragedy, she understood and didn't constrain the timelines of my revisions. Highly recommend her work!
