You forgot Narnia in your list.
Really, though, let your kids read what they're interested in reading. I read most of the works of Edgar Allen Poe in grade school (although that might not be the best example), and pretty much anything I could get my hands on in high school.
If you're worried about sex and violence -- and for some reason parents in America worry more about the former than the latter -- make sure you know what your kids are reading, and discuss what they've read. I know that's more work that assembling a whitelist, but if you restrict a kid's reading he'll find anything not on the list all the more tempting.
(I also wonder about the 12-13 category ... are those years somehow magic?)
"On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
- Charles Babbage (1791 - 1871)
