I line edit the first hundred pages; after that you should be able to follow what's gone before.
I jot notes on the mss. pages, both pro and con.
After reading the entire mss., I consider many points, among them writing ability, pace, characterization, plot, etc. and suggest ways that the writer can improve upon what's already on the page (if, indeed they can).
Each mss. is returned with a full set of notes that addresses any changes I feel need to be made.
If the writer wishes me to reread the manuscript after it's been reworked and polished, there will be a $200.00 reading fee.
I cannot recommend work with which I am unfamiliar. I have to know the writer has been able to make the necessary changes and has executed them with precision before I can recommend.
