Does anyone have any suggestions?
I find it quite hard to find fiction to interest DS1 - he isn't really into magic, would rather read non-fiction philosophy but I'm running out of philosophy aimed at kids/teens.
He likes stuff that is thought-provoking (hence the philosophy) and is currently really excited by a project at school about different planets, so I am hoping to find some child-friendly scifi to push his way. (He thinks The Martian is too long, which is a pity because I think he would like it.)
All I can think of is Nicholas Fisk from my childhood. The stuff DH and I read when we are slightly older, like Isaac Asimov and Arthur C. Clarke, is a little too old for him.
Thanks!
