Hm. A lot of the books I think people should read aren't necessarily books that I think they will enjoy. These are mostly books that will get them thinking.
1. To Kill A Mockingbird
2. Flowers for Algernon
3. Charlie and the Chocolate Factory
4. Mists of Avalon
5. Paper Towns
There are probably a ton that I am forgetting but these are some of the big ones. I will probably get some strange looks for my list but that is OK. I'm used to strange looks.
