Simply put, Lori is an outstanding editor.
Lori and I have worked together on a number of very complicated book projects over the last several years and I have found that her command of her profession, attention to detail, and admirable work ethic combine to create the best kind of collaborator.
Without question, if you enlist the aid of the Grammarwitch you will be glad that you did because her editorial abilities set her a level above her peers.
