I have worked with Melissa on one novel-length project and found her to be insightful, aggressive with the written language, and a stickler for correct punctuation. She is also capable with voice, point of view, and story arcs.
I would recommend her as a writing mentor and teacher. She is capable of excellent evaluation for fiction, and she is a good developmental and line editor.
She is probably capable of great more than I know, however, I can recommend her for the skill sets I have named. I have found her to be honest, devoted, discreet, and politely candid.
