I can't find a book!

Lately I have been searching for a good book because I just finished The Hobbit. I have no idea where to start!

Some genres that I enjoy are:
- Sci-fi
- Romance
-Non-fiction

Some current books that  I have read in these genres are The hobbit, Goergia Nicolson Series, Farhenheit 451 etc..




If you can help me find a book in any of these I would love it! I love vampire Diaries and anythinig that has to do with vampires. Currently I have been watching "Underworld" and it is a mix of all these genres.
