This sounds like a very good one, but I kind of thinking that I wasn't a huge reader as a child, so I only read a handful of books. It all kicked out in about 2005/2006. So I'm going to say pre-12 years is child. From around 12-14 it's tween or pre-teen, I think.
- Russell Troy, Monster Boy This is the book I remember as my favourite for many, many years. I can only vaguely remember the story, but I do still own it. I guess this influenced my interest in fantasy!
- My Tiny Treasury Now this is really old. It's full of little stories and poems and is something I can't get rid of because I've had it as long as I remember.
- Harry Potter This was, as I have said many times, the beginning of reading for me. I owe JK so much, in so many ways. I'm hoping she doesn't ask me to pay back for this debt I am convinced I owe her.
- Encyclopaedia of Dinosaurs and other Prehistoric Creatures I think every boy has a dinosaur phase at some point in their childhood, some even go on to do it for a career! For me, it was just an interest, a hobby. But, as always, I wanted to know everything about dinosaurs that I could, and I read this Encyclopaedia thrice through, and read sections every few months.
- Anything by Roahl Dahl Mostly Charlie and the Chocolate Factory (I loved the rhymes!) but I think I read quite a bit of his stuff. Not as much as I'd like, but a lot indeed.
- Eragon This was the borderline child-reading for me. It was a much more grown-up book, so I didn't completely understand it, but it was something I remember reading in '05 or so. Now, I don't think I'd really recommend it to a child!
- Role-Playing Books These are those books were you play a character and role dice to have your own written adventure. Apparently my dad used to like these too, so I had some very old ones a few new ones too. They're not really proper books, but I'm running out of things I read now!
- Because of how my school worked (as with many English schools and perhaps many international schools) there were always 'set reading books' that people could read and if you read enough, you advanced a reading level. When this first started, I'd consume a book a night so I did rather well in this aspect. The day I made it past levels onto 'library' was an important day for me. It meant I could read anything I wanted.
- The Dictionary....
Anyway, happy reading, hopefully with better success than my childhood self!
