Hey Laura!
I've been into Dystopian/Utopian works ever since I read 1984 by Orwell, and The Giver by Lois Lowry.
My favorites:
- Harrison Bergeron by Kurt Vonnegut

- The Ones Who Walk Away from Omelas by Ursula le Guinne

[I'm sorry I couldn't find a better link, but this is all I could find]
-The Machine Stops by E.M. Forster

If you want a full list of Dystopian literature, Wikipedia has a good one:
