Ah, the joys of revision - how I hate them! I am on my (approximately) 93rd review of the manuscript for my Martha Raye book, due out next year. It used to be that I'd kill at least a couple of trees per book, printing out pages, making edits and corrections, rinse and repeat. Now I send those drafts to my Kindle, where I spend time looking for typos, missing data, and anything else that falls short of the perfection I hope to achieve. As I go, I scribble notes to myself (see above), and then take to the word processor yet again.
There is probably no such thing as a perfect book, and mine are certainly no exception to that rule. But rest assured I am chasing those imperfections with all my might, doing my best to deliver a book readers will enjoy. Wish me luck!
