I rather like the beginning of that one. It was fun for me, to take a character that had been so very capable in the first book and show just how out of her element she was. Actually, that whole book was a lot of fun for me. I enjoyed getting to introduce all these new characters and start weaving their story together that I had known from the start and look at that, you got me book rambling without even trying.
I think I would have to go with "This is my favorite book in all the world, though I have never read it." I have a soft spot for the Princess Bride, especially since I didn't read the book until adulthood, but knew the story because I watched the movie a lot growing up. It made the line apply even more. (That's very sentimental, sorry.)
