This is probably one of Diana Wynne Jones' best books in my opinion and I love it up there with Dogsbody.
Floating castles, talking fires, bouncing scarecrows? They could only be the wonderful creations of DWJ.
I think what the author does best is create very real and very identifiable characters that somehow - you always feel you have always known. It's sort of magical how she does it, because many books may spend a few chapters establishing characters. With DWJ they just pop out at you straight away with seemingly little effort on her part.
Anyway, I think I join many girls in saying that I love Howl. I have a book crush on this guy. He's absolutely gorgeous and I want to marry him.
Howls Moving Castle makes my heart ache - with laughter. I've read it countless times and I still laugh, I still feel great every time I read it. This is one of those books that make me ridiculously happy.
