Definitely read Lord of the Flies. Golding describes things wonderful and I still shiver whenever I think of certain scenes. The symbolism is incredible and it will make you question human nature. I believe that the last page would make the entire book worthy of reading even if you hated all the rest. Which you might. It's a love-hate book. As I've said I loved it overall, but there were definitely pages or chapters where I would think "no way kids would do this!" or "Golding, I don't care what the ground sounds like, I would really like to know what's happening to so and so"
Contrary to what you might've heard, there is no cannibalism.
