Potioncat:
I agree with Geoff. It's not the themes, or darkness....it's just a 
very long book, or rather 7 very long books. Even my 13 year old has 
some difficulty sticking with it.

If it's the fantasy that he likes, I'd look for something more in line 
with his age/attention span. I don't remember if the Sword in the Stone 
would be good for his age. the book, not the movie (adorable though it 
is.) I'm pretty sure this T.H. White book inspired JKR.
