Howl's Moving Castle by Diana Wynne Jones

I read the book before I watched the animé movie. I loved them both, but having seen the movie will not spoil the book for you. There are major differences. I loved the movie, but the book explains the characters better. The book is also pretty amusing- not laugh out loud funny, but smile a lot funny. There are also two other books set in the same world with some of the same characters. I haven't read them yet, but I sure plan to!
