Well, "fiction" is an incredibly broad category (if it can even be called that). And "must read" is highly subjective ;-) If you're just looking for some light entertainment, go for sci-fi or fantasy (Lord of the Rings, anyone?). But if you don't mind some slightly "heavier" reading, have a look at the classics. In some cases they can be a little tricky to understand, but they are called "classics" for a reason... Specific suggestions (incomplete and in no particular order): Shakespeare's plays, Jane Austen's "Pride and Prejudice", Daniel Defoe's "Robinson Crusoe", Harper Lee's "To kill a mockingbird", JM Barrie's "Peter Pan", Sir Arthur Conan Doyle's Sherlock Holmes stories...
