One of my favorite books of all time has always been "The Secret Garden", which surely is also a classic, isn't it?
Some other classics I loved were "Pride and Prejudice", "To Kill a Mockingbird", "Bram Stoker's Dracula" and "Rebecca". I still haven't gotten around to read Melville and Verne, although I had planned that for years. And I certainly will read them! If you consider "The Lord of the Rings" to be a classic as well, then of course I'll include this in my list - I read it first when I was ten yers old, and I recently read it for the third time. I'm ashamed to tell, however, that I haven't read "The Hobbit" yet...

But I've read "The Silmarillion". My favorite Sherlock Holmes novel is "The Hound of Baskerville", but to be honest, that's the one I remember best. I've read about seven or eight Holmes novels, but I can't even remember the titles now, must have been ten years ago or so.
Then there's Hugo - I preferred "Les Misérables" over "Notre-Dame de Paris", (hey, my favorite character is also Eponine, and I was very annoyed that they left her out of the Bille August movie!) but no doubt both of them are equally brilliant. I just found it hard to finish "Notre-Dame" because of all the Latin quotes and the very long descriptions of a rather simple thing...
Leroux' "The Phantom of the Opera" was great, too. And then there's Shakespeare, of course - my favorites are "Hamlet" and "A Midsummer Night's Dream".
