O' Mice and Men (by John Steinbeck) ?
Try Irish literature.
Wilde and Maturin.
Not sure what counts as classic...Vanity Fair, Wuthering Heights, and Gone with the Wind are some of my favs, easy reads, and totally count as classics.
Crime and Punishment and The Plague (Camus) are great, but don't bother with War and Peace. I swear I've been trying to get through that thing for half my life.
What sort of "classic"?
I like the Tolkien books. "The Hobbit" would be easiest and shortest.
"Watership Down" by Richard Adams. "Little Women"- Louisa May Alcott. "Black Beauty"- Anna Sewell. "Fahrenheit 451" or "Something Wicked This Way Comes"- Ray Bradbury. "To Kill a Mockingbird"- Harper Lee.
I guess it will depend on reading level and what the person finds interesting as to whether these will be an interesting read.
