You might enjoy things by Ray Bradbury, one of his books "The Illustrated Man" was really good. "The Secret Annex" by Anne Frank is excellent (re-read that recently for about the 5th time). "Catcher In The Rye" by J.D. Salinger was a good one. JRR Tolkien books are wonderful, "The Hobbit" and the "Lord of the Rings" trilogy. Have you tried any of the classics? Things like the Sherlock Holmes books by Arthur Conan Doyle and Margaret Mitchell's "Gone With The Wind" are great. Mitch Albom is a wonderful contemporary author, his books include "The Five People You Meet in Heaven" and "For One More Day". I think biographies and autobiographies are interesting...just choose a book on or about someone you are curious about or admire.
There's so many good books and authors out there, it's hard to name them all!
