I must admit that even though i am a teenager I have never read twilight. Not my kind of books (i love HP though). I am way more of a classic reader, which is what most of my collection is. I loved "Slaughterhouse Five" by Kurt Vonnegut and "Johnny Got His Gun" by Dalton Trumbo, I also really love "To Kill a Mockingbird" by Harper Lee and "The Great Gatsby" by F. Scott Fitzgerald. I love Edgar Allen Poe, Jane Austen, and J.D. Salinger. I also really love William Shakespeare (actually i love plays)and Oscar Wilde.
But I also love some of the newer writters. I have, and have read, all of John Grisham's novels. I have also just discovered Corrmac Mccarthy. The Road is the best book i have read in a few years. Barbara Kingsolver is also an amazing writter (if you pick one of her books i would go with "The Poisonwood Bible" i have read it twice this year). And another really good Book is "The Gun Seller" by Hugh Laurie (yes this is Dr. House) its really good because it is Kind of a spoof of James Bond.
Right Now I am reading The Awakening by Kate Chopin.
