For those following this thread, I emailed Perry and 4wd tonight and outlined our timetable for getting through with final edits by deadline. In brief, I'm asking them to consider the Prologue through Chapter 8 done, and to concentrate on the remaining chapters with an eye out just for these things: tautologies, logic errors, typos, and other grammatical errors.
Then, lf we get the book drudged for those bottom-feeders, we can go back and leisurely tweak phrasing, and do other polishing. The goal for right now, however, is to rid the book of any remaining outright errors prior to my deadline.
