There are some books that everyone should read. To kill a mocking bird. The Grapes of Wrath. Republic. Lord of the flies. Animal farm. Go tell it on the mountain. It's good to look at the world through someone elses eyes.
If you're into a good series, think that classic books like To Kill a Mockingbird are dull, and enjoy fiction, I recommend these: Gregor the Overlander, I Am Number Four, Percy Jackson and the Olympians, and if you don't mind vampires, Eighth Grade Bites. I'm not putting down classics, I just find them boring since they reflect real life in its own tale.
