Oh my gosh I LOVE Kristin Lavransdatter! I just reread it last year. To answer your question, no I don't feel the same way when reading books - if I liked it enough to reread, then I really really liked it, but I don't usually have a strong emotional reaction. With KL specifically, I was hugely judgmental of her when I first read it when I was 23 (although I very much enjoyed the book). Now that I have my own marriage and child and life, I still felt that I would have made vastly different decisions (I didn't think Simon Darre was that bad of a catch lol, even at 23), but I came to her story with a very sympathetic heart this time around. If I feel lost, it is after reading, unable to move on to anything else for a few weeks because nothing can measure up.
