But there was this method to her remorselessness: she calculated that she could not clean this thoroughly without sooner or later coming across Howl's hidden hoard of girls' souls, or chewed hearts - or else something that explained Calcifer's contract. p.68I love Diana Wynne Jones. I was obsessed with her Chrestomanci books when I was younger and that lead me to Howl's Moving Castle. I hadn't read it in at least 10 years, but the other day I was watching the movie and I decided I need to read it again. It is a slower moving book, less action than some books especially in a fantasy, but it is such a good book. I thoroughly enjoyed it as much as an adult as I did when I was a child. Sophie is such a funny, plain girl, but after she becomes an old woman she gets really feisty and funny. Howl is very selfish and odd, but he can be kind as well and the scenes with the two of them are great. Calcifer, though, is one of my favorite characters (I must have a soft spot for demons (I'm looking at you, Bartimaeus.)) and I like the whole story of the Witch of the Waste and where Howl originates from. It makes it more fun.
*spoiler for the book*) is the removal of Sophie's magical powers. I love that part of the book and I wished they could have included it.
Read the Book, See the Movie
