She won't listen to books read aloud--"Too slow!" (I feel the same way myself, actually.) She'll make an exception for book on tape in the car, though...but I don't know that something at a "bump up" level for her could really work for DS4.
I think she would like Tolkien, and is probably ready for at least the Hobbit. (One issue is the lack of significant female characters--she is VERY attuned to that. She won't read Harry Potter for this reason, among others. "It's all about a boy!") I can't decide if I should take her to the movie when it comes out or not.
Cressida Crowell and Diana Wynne Jones--how are they for female characters? Is it knights and dragons? (She's not into that.)
