"Pride and Prejudice" by Jane Austen is an excellent classic romance book. I usually don't like romance books. They usually seems flat and uninteresting to me. However, Austen is an author I love to read. Not only does this book handle Elizabeth's and Mr. Darcy's character growth into lovers. Austen handles themes of class differences, gender roles, and family connections. This novel is more than just a one dimensional romance story. This is a story about the interactions of people and how they handle those interactions. "Pride and Prejudice" is a novel that I highly recommend.
An excellent classic book with many movie adaptions. It goes over the state of the soul, vanity, corruption, and beauty. The main character, Dorian Gray, keeps putting the blame of his actions and state onto the picture of himself that has been cursed. He believes that if you have beauty, you have everything no matter how decadent, vile, or corrupt you are. He keeps forgetting that he placed the curse and he is doing the actions that are being placed on the picture. He values his beauty more than his soul.
A good classic book written in the 1800's by Mary Shelly. It explores questions about secrecy, knowledge, ambition, and monstrosities. While reading this book, one needs to question who is really the monster; the creature or the creator/humanity? Also, ask how far one can be pushed and ostracized before they crack and do horrible things to those around them.
It is a book that should be read by everyone and explore the questions asked.
