  • “Caylah is definitely a qualified editor! Not only in schooling, but also in thought and temperament. She has a discerning eye, a wonderful read on a manuscript as a whole, and the creative mind to offer really insightful advice.”

    Hana Kat, Writer & Poet

  • “Caylah has a knack for spotting issues with the pacing or the “feel” of a scene. Her comments are encouraging and helpful: instead of simply pointing out flaws, she makes sure to suggest improvements. She’s also good at including positive feedback and noting aspects of the story that really worked for her.”

    Galadriel C., author of The Case of the Dragon-Bone Engine

  • “Caylah Coffeen is an editor I try to emulate. She not only has an excellent sense of pacing and tone, she gives feedback in a way that suggests growth and makes me feel energized rather than frustrated at a list of problems.”

    Anneliese Knop, co-author of Jubilant
