I'm not much of a re-reader as I've always been more into a novel experience. Sometimes I'll read a book again if it's in a series and I need a refresher before the next one comes out, but I've never felt that pull to dive back into a book, even if I really loved it. I have been feeling that a bit for LeGuin's Earthsea series recently, which I last read in my childhood. Also a bit for Ennis's Leech, which I read much more recently.
For those of you who are like me, what do you find pulls you into reading a book again, on the rare occurrence when it does?
If you do love to read the same books again and again, is there something in particular that sets them apart from other books you may have really liked but don't pull you back in a second time?
