I am a huge Howl's moving castle fan, and although I wished there was more of Howl and Sophie, this is a really good read all on its own. I'm a little older than the target market, but I tend to read anything that's magical or mythical. It has all of Wynne-Jones quaint charm in her writing, her tough no-nonsense female protagonist, and the very warm and well rounded characters. If you loved Howl's moving castle, then this is definitely worth a look. Castle in the air was passable to me but it doesn't touch the house of many ways. As I read I kept waiting for Howl and Sophie to turn up, but the story made me forget all about it until they showed up. I would recommend!
