How is the book selling? Well, Barnes & Noble sold 24,000 copies in the first six days they had it for sale -- making it their number one seller for the week.
I went to Amazon's book pages. Amazon has it listed fourth in their top 100 books (and are calling it the hottest new release they have). That's pretty impressive considering the book has only been out for a week.
Congratulations Hillary! I hope the book has to go into a second printing.
