Dune, by Frank Herbert, is considered by many to be the greatest Science Fiction novel of all time.
I loved Dune but found each of the five sequels to be weaker than the last.
When Dave Adlard recommended yet more books set in the Dune Universe, I was dubious.
Prelude to Dune is a “a prequel trilogy of novels written by Brian Herbert and Kevin J. Anderson.”
Brian is Frank’s son. The prequels were written after Frank’s death, based on original notes.
Dune: House Atreides chronicles the early life of Leto Atreides, prince of a minor House in the galactic Imperium. The novel begins on the planet of Arrakis, 35 years before the events of the original novel Dune.
We meet Duncan Idaho, only 7yrs-old. And learn more about the history of houses Atreides and Harkonnen, their bitter feud.
So far as I’m concerned, this prequel is as good or better than Dune itself. An impressive feat.
Thanks Dave.
The first film of Dune was adapted by David Lynch (1984). Frank Herbert liked it. As did I.
There’s another film version in the works. No date of release has yet been announced.

I listened to the whole Dune series, and then the prequels about 8 months ago. A huge time investment, but I enjoyed the whole thing. I think I had maybe read the first 4 novels in the Dune series when they first came out, and it was good to hear them again and the continue with all the new stuff. The prequels were all good, and I was impressed at how they fleshed out the characters that I already knew. And knowing how it was going to end didn’t affect my enjoyment of them.
I think that the other prequel books “The Legends of Dune” trilogy, which go back all the way to the fabled “Butlerian Jihad” and explain about everything, including warp drive, where the Bene Gesserit and mentats come from etc, are even better… they REALLY flesh out the formation of the Dune universe, and probably should be read before the Prelude series, even.
The last books, Paul of Dune, Sandworms, etc are equally good, and tie all loose ends up. Read them last, though!
