Out of these classic novels which one would you highly recommend ?

The Catcher in the Rye is brilliant, in my opinion. Thought-provoking and certainly "worthwhile", but also an easy read and hugely entertaining. I was really intrigued by the concept of As I Lay Dying at one point, but I'm about halfway through it right now and finding it quite hard to get any further... try at you own risk, I'd say. From your link, another favourite of mine is Jane Eyre, and although I haven't read it yet, I've had some friends recommend Brave New World. Since you're already considering it though, The Catcher in the Rye is my suggestion :)
