Yep, Kermit gets it. That's exactly how I feel, excited and freaking out all at the same time. What I'm learning is that putting a book has a weird arc. There's this very exciting part at the beginning of signing a contract, dealing with edits, etc.
Then there's this very-long-feeling part in the middle where lots is happening, but you're not the one doing all that stuff (this is a traditional, small press publication). People at the publishing house are working diligently, but you're just kind of waiting, hoping someone will send you news or images of your book cover, promotional opportunities, etc. If the publishing process was a novel, this is the messy middle and the editor would have me trying to liven it up!
Now, I'm in the tail--where I have a lot to do again. I'm reading the galleys, finding any last minute errors that survived the process so they can be corrected before print. All those promotional things I've been lining up (interviews, guest blog posts, etc.) are now due! My correspondence time commitment is crazy-high.
My goodreads page went active, my amazon author page went up, and my book is up for pre-order at least in Kindle format. And all of that happened in the space of a week.
So, if you see me looking a little lost, turn me around and send me back home--I've got a lot of tasks on my plate; I shouldn't just be wandering around like that!
