I'm sure we all know several classics, but here are some that came to my mind:
- The Great Gatsby by F. Scott Fitzgerald
- Pride and Prejudice by Jane Austen
- Dracula by Bram Stoker
- Little Women by Louisa May Alcott
- Animal Farm by George Orwell
- To Kill a Mockingbird by Harper Lee
- Frankenstein by Mary Wollstonecraft Shelley
