And I wouldn't want to force a book on him - I can remember only too well being back at school and being force-fed books to read, and I'd hate them on pure principle!

He is nothing like the voracious bookworm I was at his age, but he doesn't have time nor the inclination. That hasn't translated into an immature ability but he would likely tell you some choice words if you tried to get him to read most of those books on that list.
Do I care? Not really. He will likely read some of the listed stories in his own time and if not then the world won't end. I'm happy seeing my sports-mad ball of energy sitting for hours fascinated with a pile of Nat Geo magazines, or explaining Zac Power's latest gadgets to me.

Books should be treasures we discover along the way, not geegaws forced upon us by someone else. I've not read past the fourth chapter in the first book of LoTR for this very reason. I have the feeling I'm missing out on a really ripping yarn but I can't make myself do it; I imagine it's for a similar reason as for kids who were forced to eat porridge, growing up and never eating it again.
