Patrick Ness's top 10 'unsuitable' books for teenagers - Guardian article

"…There are a number of books that are actually rather better if read when you're a teen, some because they're entertaining contraband, some because it can never be too early to read something so wonderful, and some because, if you wait, you might have missed your chance forever."

1. The Catcher in the Rye by JD Salinger
The obvious first choice, but not necessarily because of its literary reputation. It needs to be read when you're young. If you first meet Holden Caulfield when you're too old, the
desire to give him a good slap might impede your enjoyment.

2. The Stand by Stephen King

For his sheer ability to get teenagers to love reading, Stephen King is a saint. I did a book report on Pet Sematary in 8th grade. My English teacher, bless her forever, gave me an A. I pick The Stand because if you're an adult, it's a bit long. If you're a teenager, it's War and Peace. Scratch that, if you're a teenager, it's better. And that's no bad thing.

3. Infinite Jest by David Foster Wallace
Speaking of 1000+ page books, Infinite Jest is filled with all the things that are brilliant to read when you're young: unembarrassed cleverness, a cheeky take on the future, hilarious experiments with form, and a serious sense of accomplishment when you're finished.

4. Beloved by Toni Morrison
I read Beloved when I was 15, and it felt like the first time being allowed to sit at the grown-up's table. I may not have followed every word, but I was mesmerised. And I learned without even knowing I was being taught.

Frankly I would have included Junk and Clockwork Orange in there. They seem to have turned out to be well thumbed operations manuals for teenagers rather than anything educational.
