Howl's Moving Castle

I don't think I can empathise enough how much I love that book.
Some or even many people may know the move adaption by Ghibli and I can tell you it is nothing compared to the book! So when you like the film I guarantee you you'll love the book.
Only after reading it I understand some of the scences in the movie, so go on and read it while I wait for the other two volumes to arrive at my local bookstore ;D
