Ooh, Harrison Ford as Graff - I can totally see that. And I agree with you about the ages of the kids. Reminds me that in my children's lit class the textbook rec'ed Ender's Game as a good Elem (K-5) level book, and as I was doing a presentation on that chapter (Sci-Fi/Fantasy, ya'know I jumped on that one) I pointed out that it was not for that age group. The only thing I can figure is the author of the text saw the ages of the protags and just figured it was aimed at that age (!).

Glad you're getting some good reading time in!
