From her diary, J. K. Rowling talks about ending the Harry Potter series with the upcoming 7th book.  Just like many Harry Potter fans, the author feels a mixture of sadness and joy.

“Even while I’m mourning, though, I feel an incredible sense of achievement. I can hardly believe that I’ve finally written the ending I’ve been planning for so many years. I’ve never felt such a mixture of extreme emotions in my life, never dreamed I could feel simultaneously heartbroken and euphoric,” she writes.

“I’m almost scared to admit this, but one thing has stopped me collapsing in a puddle of misery on the floor. While each of the previous Potter books has strong claims on my affections, ‘Deathly Hallows’ is my favorite, and that is the most wonderful way to finish the series.”
