Let me count the ways.
Terrified. Because what if people hate it?
Stressed out. Because what if no one buys it, and your publisher is disappointed?
Cranky. Because promoting a book is not all that fun.
Okay, so maybe I don't know for certain that's how other authors feel. I just know how I feel.
J.K., you ever feel terrified, stressed out and cranky before a book's release?
Maybe she did. Who knows? Waiting to see how fans reacted to the last book in the series probably wasn't a ton of fun. Although, pretty sure she didn't have to worry too much about disappointing her publisher, right? :)
