In I Am Number Four, the Mogadorians have tracked down and killed the writers of the newsletter They Walk Among Us. But someone is continuing with the newsletter, sending out updates of what is happening to John and the rest of the Lorien Nine. Could it be a trap planted by the Mogadorians, or is it someone trying to help them? In the B&N exclusive version of The Power of Six, a new issue of the newsletter will be included in the back of the book as an eight-page gatefold, and it will be perforated for easy removal.
