I need some a few books to read. I don't like romance or fantasy. I'm mature for my age but, I want young adult books that are well written and have a good theme in it. Some of the books I've read are: The Soloist, Animal Farm, Lord of the Flies, The Curious Case of the Dog in the Night-time, and The Perks of Being a Wallflower. Are there any books or authors similar to them?
