Which book should I read?

ok. so I've only completely read one of these books and that is fahrenheit 451. Its a fairly easy book to understand, I had to read it for my last year of High school. I enjoyed reading the book off and on, it was a little strange for me what with the futuristic stuff and all. BTW I'm not a big futuristic fan. Jane Austen is a great author I read some of her work, but writers from the 19th century are very hard to understand. But still great book. The same for Great Expectations I have the book, I tried reading it, but the way of writing psyched me out and I didn't finish it. I also have 'The Diary of Anne Frank' is a good biography I have that same book. It's pretty long, but it's heartfelt, easy to understand and it makes you empathize with what she is going through. Good luck on whichever book you decide to choose.
