So, Marsha? Re: Doctor Sleep, I just have this one last question for Stephen....

So far it hasn't been hard. My father passed away after I was contracted to do my first book, so I dedicated it to him, and updated it to include my mother for the limited edition. I dedicated my second book to my wife and my latest one to our daughter (whose boyfriend drew the illustration for the limited edition, by the way). The next one, though, if and when it happens, will be tougher, since I've now dedicated books to the most important people in my life.
I believe that Robert B. Parker dedicated all (or most) of his books to his wife.
