Castle in the Air - Diana Wynne Jones More than 4 stars, it should be 3 and a half. True, it started a little slow and it's not as entertaining as Howl's Moving Castle, but it still has that charming touch of the first book. Of course, I've specially loved when familiar characters started to appear, and in the end, looked as everyone (Howl, Calcifer, Sophie) was in the story as someone else. Relly funny and lovely.
