You can approach the story from a variety of angles.
- It’s a ecological tale (written in 1965!) about the desire to work with a planet’s environment to create a healthy future.
- It’s a political tale about the endless subterfuge employed by the power-brokers of the world.
- It’s a religious tale about the results of spirituality on a culture.
- It’s a philosophical tale about determinism and destiny.
- It’s an action adventure story (with a dash of mystery) set in a fully realized alternate universe.
It’s simply engaging on every level.
Fortunately, Herbert went on to write a number of follow-up novels. Other authors have continued after him to write in his world. I’ll be able to take plenty of trips back to Arrakis.
