Dune by Frank Herbert

Classic science fiction. It is an epic with all of the right kind of plot twists and events and characters. It is the kind of book that is hard just to fly quickly through - as there are so many layers and details and connections throughout. It is not light reading, nor something that makes you quickly satisfied - instead it is a book that provokes thought and desires re-reading. And the book is slightly bittersweet, even if good is shown to win.
