Books 2 and 4 of the Wool series have disappeared from the Kindle store. For those of you wondering why this is, I have no freakin' clue. And there's no one I can get on the phone to explain the problem or get it fixed. This is happening with some other books, so it appears to be a glitch on their end. I apologize for any frustration/confusion. If you're reading along in the series, I recommend returning what you've already purchased and going for the Omnibus Edition. Let's hope that one doesn't up and vanish as well!
