I am a big fan of Leo Tolstoy. His biggest works are War and Peace and Anna Karenina, but those are both quite large, so if you want to know a bit about his style i would suggest some of his shorter works. Of the shorter works I have read I really loved "The Death Of Ivan Ilyich", "Hadji Murad" and "Master And Man".

I also really like Jane Austen, you can't really go wrong with her. Her novels aren't that difficult either; they were the first novels in English (my second language) that I really enjoyed reading and they significantly improved my English.
