Positive Book and Other Media Recommendations for a Teen Audience

Hi Less Wrong,

I’ve got the opportunity to promote books and other forms of content to a largely teenage audience. I’m looking for some good book recommendations and recommendations for a limited amount of other media (websites, movies, etc) that will spread awareness of positive ideas and issues in the world, while still being entertaining to the target audience. HPMOR comes to mind, and although I don’t think its main focus is to promote an issue to readers, it is an excellent choice because it is well ranked, promotes rationality which can directly help readers, and is completely free to read online. Recommendations don’t have to be free, but that is a very important factor.

Thanks everyone!

Edit: Thanks everyone for your contributions. I realize I was being a little too vague, I think content that promotes ethical/​altruistic behavior is mainly what I am looking for, either inspiring it with fiction or causing motivation for it with nonfiction. I am looking for free web content, although paid content recommendations are also appreciated. This is for a general youth audience, not a club or any sort of interest group.
