Since we're talking about what makes you abandon a book, I was just curious what makes you re-read a book. I have a single shelf in my den which is reserved for those books I love so much that I won't get rid of them just in case I need to give them a re-read. They are books from several genres, not all of them are fantasy related, but I am in love with them all.
Do you have a special place for books you can't part with? What makes these books so special?
