No, it's an extra chapter Stephenie released with the paperback edtion of the book. She wrote the chapter in Melanie's POV. It's just supposed to fill in the gaps of what happned during those blank pages when Wanderer was in hibernation.
yeah, ill try to get someone to send it to me, i really want to read it now that i know it exists..
maybe stephenie will write a second book with someone else's point of view now that wanda isnt in melanie
