Despite many edits, I just didn't know how to write yet, so didn't avoid common pitfalls that befall first-time writers: wordiness, "telling" not "showing", character head hopping, misuse of dialogue tags, misplaced modifiers, forgetting the timeline (or bouncing around in time), and the dreaded passive voice. They let me know what I needed to do to get my book back on track. I am truly indebted to them for their time and expertise.
