Howl, Sophie, and Calcifer from "Howl's Moving Castle" by Diana Wynne Jones.
I love the book, much more than the movie! I mean, the movie was beautiful to watch, but it just didn't make any sense, at least to me. The book made much more sense. But I do like the part in the movie where Sophie falls into the random black hole and screams "Find me in the futuuuure!"
Me too! There were so many moments in the book where I laughed so hard I almost started crying Loved the bickering between Sophie and Howl - so much fun!
