Blood Meridian

I received this book from my Secret Santa a while ago and decided to bring it to read in Portugal. I was really getting into the book, it can take a wee while with his books, when I noticed a chunk of the book was missing! I emailed the publisher, who sent me out a new copy which is wating for me in the U.K. This is the second time this has happened to me, the first was even more annoying as the very last chapter of the book was replaced by the first one! I had a long weekend to wait before I could exchange it. I wonder how often this happens?
