I was given one of his books as an 11 year old, and have a very clear memory of feeling very much 'at home' while reading/working with it.
I got one of his books for DS and there was not much interest.

He's great for the 'like to look at old things in new ways'/old soul/humanities/Imaginational OE sort of kid.

Hope that helps,
Grinity
