Haha, I've just read Lord of the Flies too... and totally loved it. I was familiar with the play but the book is so much better. Such a great book.
I also read Animal Farm which is equally brilliant... I love the documentary style narrative and the way that complex political ideas are presented through such a simple and accessible allegory.
And at the moment I'm reading The Excorcist (yep, the book of the film) which is surpisingly enjoyable. Recomended to anyone interested in the paranormal.
