Query: Dune: Ignore that it is sci-fi and take its message to heart

I will say this as concise as I can: Dune is a great novel. Sci-fi adventure is there, but if you dig deeper, you may be suprised to find an excellent cross-section of religion, ecology, politics, and business. There are many themes that you can follow throughout the book, or you can just read it superficially and be overwhelmed by the tide of complexity.I read it for my first time this month, I am 24. I wish I had read it sooner. I reccomend this book to the young Sci-Fi reader (there are battles and giant worms and space craft), to the young adult (learn a little about how fuedal politics work as well as conservation), and the adult alike (apply water discipline to your business and see how it changes).A book that transcends the author and format itself, a true marvel of writing. No wonder it has a cult following, which I now belong to. Now, we just need a few more decent web sites devoted to it.....
