DS is a good reader, casting around for what to read next, and I am wondering whether he would like some Sci Fi (in the broadest sense)
Terry Pratchett? If so, where to start?
The CS Lewis sci-fi (or too difficult)
Asimov prob will make his head hurt, no?
He likes fantasy, but not 'magic'/wizardry like Harry Potter.
Any other suggestions? It wasn't really what I read at his age.
Thanks
