In its first week after publication, "New Moon" reached No. 5 on "The New York Times" Best Seller list for Children's Chapter Books, and in its second week rose to the No. 1 position, where it remained for the next 11 weeks. In total, it spent over 50 weeks on the list. In May 2007, Meyer held two promotional prom events at an Arizona State University gymnasium to celebrate the special edition release of "New Moon" and the release of "Eclipse". For the event, Meyer wore a blood-red evening gown and signed over 1,000 books. Meyer's red dress was later auctioned for $5,500 at a fundraiser for a book seller's battle with breast cancer called Project Book Babe.
