Dune is the greatest Science Fiction novel ever written. It has action, romance, political intrigue and more. It's set in a very well realized universe, and the characters are believable and, for the most part, either likable, or utter bastards who are so well written you can't help but admire them. Or both, in some cases.
I first read Dune when I was 12, and, to be honest, I think most of it went over my head. Still, I loved it. Every year since then, I've read it once a year, at least. Each time I read it, I notice something else, get more out of it, enjoy it even more. Last year, my copy fell apart, so I had to buy it again. Which brings me to now.
I decided to get this copy, which includes the first two sequels, as it wasn't much more expensive than just ‘Dune’ on it's own. I can't really say much more about it without revealing some important spoilers, and so I'm going to wrap up the review here.
So, all I can say to you now is “Read Dune. You won't regret it.”
