Challenge: Read a book that was turned into a major motion picture.
For those of you who haven't seen Howl's Moving Castle, it's an anime about a girl who is cursed by a wicked witch and searching for the Wizard Howl to fix the curse. Sort of..in a nutshell. The book, however, is much, much different than the movie. Some people I've talked to who read it after watching the movie didn't like it at all. I enjoyed it. Yes, it was much different, but because I knew this going into the book, I tried not to hold too closely to the movie in predicting the book. It's a fun fantasy read.
