Updated Book Two's title in the sneak preview at the end of Book One

After my little anxiety attack about that line in chapter 5 of book two and making the one-word change associated with it, I figured while I was at it, I'd also update the ebook and paperback of book one where I have a sneak preview of book two at the end, to reflect the updated spelling of book two's title. So I guess that will result in more existing copies becoming collectors editions someday in the far future.
