Revising... Editing... Aching back...

Each night for the past week, my back aches when I crawl into bed.  I pulled up the soft sheet and blanket, get warm, and drift off to Neverland.   Often exhausted from the revising and editing I have been doing on the first half of my book.   The changes, in my opinion, has added more flavor, a deeper sense of Sam's life, and better direction of what he needs to learn.  After all, he is the protagonist of the story.  However, I was shocked at who turned out to be the antagonist.
