Howl’s Moving Castle
World of Howl #1
a young woman is turned into an old woman by a jealous witch. She ends up becoming the cleaning lady for the wizard Howl in an attempt to get him to turn her back. The jealous witch is after Howl. Everything turns out ok in the end. I would have to recommend reading this before watching the movie by Miyazaki. A much more full bodied story and things are explained a bit more.
