It may come as a surprise to some, but there were books around when I was a member of that age cohort.
And propping up the short leg on the table was NOT the only thing we used them for...
Anyhoo, what
I (lotta i's typin that...) remember reading and enjoying would be what I'd recommend. Like:
All Edgar Allen Poe. I spent my allowance on a biiig book "The complete works of..." or something like that. Truly dug it. Not non-fiction, but it fed the majority of my fantasy life: Road and Track, Car and Driver, and Motor Trend (weak sister...). I include these in spite of your request for fiction because I believe that reading is contagious. Read what you like and you'll like reading more and it just goes round and round and round. There'll be some fiction in the mix soon enough. For the preteens in my current circle, number one with a bullet is anything and everything Calvin and Hobbes. Um, yeah, they're MINE and I share them grudgingly (hey! careful with that cover!!!) I could post pics of SonofV sleeping with Calvin and Hobbes flopped onto his face.
The Harry Potter suite is very enjoyable. I read a ton of Heinlein in my yout.
One other advice-y part, the kids will follow your lead. Let'em catch you reading too. Have abundant books around. We have a ton of movies and video games, but for every one of those, we have ten books. They don't have to be your books, btw. Go to the library. [/sermon]
Good luck, report back, I'd like to share your success!
