I know the feeling. That is one reason I replaced a lot of my books in Hardback, since it is a little harder to destroy do to over reading (not that I haven't managed it). In the paperback version of When Darkness Falls the first 20 pages or so is completely out of the binding (that is the one in the best condition), and I don't have a whole lot of confidence that the rest of series is any better. The condition of that series would make any book lover cry. But that was one of my favorite series (till the Dragon Prophecy started coming out) so it was the first one I replaced in hardback. Also have all those in my e-book, at least then it can't get destroyed and I can count on the fact all the pages will be there.
