I Need Suggestions On A Good English/british Novel (i Have To Have A Book Picked Out By Tomorrow)?

I am in Honors English at my school, and we are required to read a British novel following an analysis essay that is must be turned in at the end of the marking period. My problem is that I can not find a good British novel to read due to the fact that I have already read it; We are going to read or have read it as a class (we have to pick a book that is separate from the ones we are going to or have read in class).
Here are the books I have already read:
-1984(I loved this books so much, I like any books involving dystopia)
-A Clockwork Orange (Amazing book)
-Great expectations
-Oliver Twist
-Brave New World
-Frankenstein(Just finished and absolutely loved it)
-Dracula
-Dr.Jekyll and Mr.Hyde
-The Hobbit
-Lord of the Rings trilogy
-Gulliver’s Travels
-Lord of the Flies
-David Copperfield
Yeah….. So you can kind of see my problem. I have read a lot of books. By the way my favorite books are Dystopia’s or any books that, for lack of better words mind f**k you. Also, I like science fiction.
