A while back, we got into a discussion regarding P.O.V. I made assertions, believing wholeheartedly (based on previous study) that my perception of POV was solid. After much debate, I began to realize I didn't have it nailed down nearly as well as I thought.
After that discussion I purchased a book teaching POV. I've read it cover to cover (twice) and still, I feel like your understanding of POV may be more thorough than what was in the book that I purchased (Written by respected fiction author Nancy Kress).
I am hereby requesting that you please consider writing a POV instruction book. If you were to write it and publish it, you have at least one guaranteed sale from me.
