It has been our pleasure to work with Kasia as copy-editor for our recent book. She is meticulous and proved to be gifted in identifying ways to improve the clarity of our writing. We recommend her services whole-heartedly.

Vikram Patel and Charlotte Hanlon, authors of "Where There is No Psychiatrist", 2nd edn

Kasia is an outstanding editor and was a joy to work with at every stage. All her suggestions were very helpful and greatly improved the text. She is a rare jewel.

Agnieszka Kołakowska, writer and translator

I just wanted to thank you for your excellent work. I have really appreciated your willingness to adapt and be flexible, particularly with the changing nature of the materials and have found all your mark ups to be really thorough and clear for the designer.

Kasia is a very capable, thoughtful and conscientious copy-editor. She has an excellent grasp of style and syntax, and is sensitive to the aims of the text in relation to page layout and design.
