I would like to specifically highlight his editorial approach: it was an extraordinarily careful, subtle, and gentle work with the text. Mr. Serhiy did not try to "rewrite the author to fit himself," did not break the style, did not intrude harshly into the intonation or presentation, but rather — very gently enhanced the text while preserving my authorial voice. This was especially valuable to me.
Regarding beta reading, the feedback was substantial, precise, and truly helpful. The comments were spot-on, the observations were deep, and the recommendations were relevant and actionable for further work. I know what I still want to work on in the novel.
I recommend Mr. Serhiy as a thoughtful beta reader and editor who works professionally, delicately, and with respect for the author's text.
