There have been plenty of books that I have been reprimanded for, but only by my parents. One was "Fade" by Robert Cormier, The Phantom Tollbooth, Piers Anthony's Xanth series, and C.S. Lewis' "Chronicles of Narnia" were nixed also. I don't remember particular reasons, fantasy was a no-no in our house.
I'm pretty sure my parents didn't realize that Narnia was supposed to be Lewis' version of Christian ideas for kids.
Ah well, atleast there's one advantage of growing-up, lack of parents telling one what and what not to read.

I used to sneak read at night with a flashlight.

One of the reasons I read so much is that, though many movies and TV shows were unavailable to me (we moved a lot, usually to very remote small towns and foreign countries), I was allowed to read anything I wanted from the library. I dove into the science fiction shelves and general fiction at an early age. I avoided the children's and young-adult sections because the stuff I found in the "grown-up" sections were so much more fascinating. By the time we had other media available to me, I found them un-interesting compared to books.

I don't watch TV anymore and watch only select movies. Still reading up a storm and loving it.

I did, however, get in trouble for reading in classes where I should've been listening...

There were two things my mother didn't want me reading before I was fifteen, that I had tried to. The Bee Season, and Perfume, both because of very screwed up explicit content. Didn't stop me though. I used to also get in trouble during my government class in high school for reading through lectures.

People seem taken aback when I'm asked what my favorite book/author is, and my answer is Lolita by Nabokov.

My guess is they are upset about the subject matter, but anyone that's read his writing has to give it up, it's like the whole thing is a massive poetic compostition.

I discovered, and became obsessed with, mythology in first grade, while attending a catholic school.

I remember asking the nun in religion class why our God didn't have interaction with everyday people like the Greek, Roman and Egyptian Gods did, and why our God wasn't as much fun.

In third grade, I compared the old testement bible stories to Greek & Roman mythology in a different nun's class.

"The Story of O"
Made the mistake of reading it in class when I was in highschool. I got the same "don't bring that trash into my class" bullshit

Not from reading a book, but got a mild rebuke for reading Playboy...a friend in middle school smuggled his dad's Playboy collection and doled them out to trusted friends and associates. I was sitting in typing class, reading an interview by my favorite author at the time (Ray Bradbury, in case you were wondering...), when one of my snarky female classmates ratted me out. The only thing that saved my bacon that day was the fact that my typing teacher knew what a goober I was and when I told her that I was reading the article, she believed me. Mrs. Klein told me to put "whatever" I was reading away and to remember this was a typing class, not a literature class. God bless her, she was a pal!
