Sarah Palin's book is due for release subsequent month, (November), why have it be number 1 within sale since August?

Sarah Palin hadn't finished her book when the release date was estimated for January, but then changed to November.

However, since the book announcement, her book then become the number one seller and it still hasn't been released, yet.

The book have been number one in sales for adjectives that time. Why?
