Palin 'grateful' for top spot. "This book has taken off like a rocket," source said.

Two days after the release date of Sarah Palin’s book was announced, it's already become the top seller at both Amazon.com and BarnesandNoble.com.
Palin’s publisher announced Monday that the former governor of Alaska and Republican vice presidential candidate had finished her memoir, "Going Rogue: An American Life," early and was moving the release date up from the spring to November 17.
A Palin source told POLITICO that she "is very grateful" for the strong early sales.
"This book has taken off like a rocket," the source said.
HarperCollins will print 1.5 million copies for the book’s first run, the same number that was printed for late Sen. Ted Kennedy’s memoir "True Compass."
Kennedy’s book, published earlier this month, currently stands at number six on the Amazon list.
A publishing industry source told POLITICO that they "cannot remember a non-fiction book taking off like this in the pre-order market. It became number one only a couple of hours after nothing more than a date announcement. It is truly unprecedented." (continues here at POLITICO)
