1. Anna Karenina by Leo TolstoyNow this list is terribly heavy on modern writers. In fact, the oldest book on the list is Hamlet (early 17th century). Where is Homer? Where is Virgil? Where is Dante? In fact, there is no poetry on the list at all. Maybe that is intentional, but it is still unfortunate.
2. Madame Bovary by Gustave Flaubert
3. War and Peace by Leo Tolstoy
4. Lolita by Vladimir Nabokov
5. The Adventures of Huckleberry Finn by Mark Twain
6. Hamlet by William Shakespeare
7. The Great Gatsby F. Scott Fitzgerald
8. In Search of Lost Time by Marcel Proust
9. The Stories of Anton Chekhov by Anton Chekhov
10. Middlemarch by George Eliot
And why two Tolstoy's and no Dostoevsky?
Well, it's a good discussion starter anyway.
