Is the Howl trilogy worth reading? I've read the first Howl's Moving Castle and it's really great but do you think Castle In The Air and House Of Many Ways are worth reading?

I really want to know what you think.

i haven't read the second one, but I read the third one (house of many ways) years ago and I liked it, though the first book is better as it often happens
