Katrina was really great! She gave me the feedback I needed to hear so that I could improve my style and help me strengthen my writing for the future. She's given me a lot to think about so that I can take action in my book.
Kate Elizabeth, December 2020
I received your assessment. Harsh as reality presents itself, don’t discount the information you have afforded me. Since I can count on your honest assessment, would you be willing to likewise edit the next novel in this series called “The Bus Orphan?” If so, please send me an identical contract to the last one. This novel has less than 40k words, but needs the same viewpoint you can give me.
