Client testimonials

“Mercer is a skilled writer with a keen editorial eye. She reads deeply, and her feedback is both astute and kind. I’ve relied on her insights for several of my manuscripts, and she’s always helped me to enhance what was working, pinpoint missteps, and identify areas that were ripe for improvement.”

-Karla Manternach, author of Meena Meets her Match, and Never Fear, Meena’s Here!


“I’ve gone through all of the editorial feedback you’ve provided for both books and I am super pleased. Having gone through the comments and made many of the changes suggested, you’ve made my writing much stronger. I love your reports, by the way, that’s a really nice way to identify the bigger, more recurring issues and I particularly liked the comments on style, which were particularly useful and insightful. Delighted you got recommended to me.”

“I’ve always been a proud pantser when writing my first drafts. I didn’t believe in outlining or plotting because I thought it’d hamper my creativity. When I participated in the plot graphing workshop, I was hoping to glean a few tips, but I ended up loving the process of laying out plot, characters, and conflicts. I used the plot graph to map out my newest Work in Progress, and not only has it helped me write faster with more sense of clarity, it’s also allowed me to maintain my creativity. Now I’m a proud plotter!”

“Joanna helped me work wonders with my manuscript! I needed help with characterization and pulling together the plot more concisely. She had an idea…and at first, I thought no I can’t do that! But guess what? It was exactly the thing that needed to happen to bring my story together. It was hard and scary and a ton of work, but the result is So Much Better. One of my characters is now incredibly complex, whereas before he was just someone along for the ride. There were some plot points that needed to pull through a little more, and Joanna had some great ideas – most of which I used. Her in-line commentary was enlightening, and in the one week she had my manuscript, she read it more than once and gave commentary during both the first and second readings. Joanna also pointed out some problems I had with “telling the reader” what I already “showed the reader,” through either character actions or dialogue. One key lesson I learned is to trust in my storytelling, and for that I’m thankful. Never once were her comments condescending – all of her feedback was honest and straightforward and given in the spirit of truly wanting my manuscript to be the best it could be. She’s professional in all her communications. She always let me know where she was in the process and gave estimates of when she’d be finished, and was generous in her availability to answer questions or talk through some of her ideas. I hope to work with her again on a future manuscript.”
