The Butlerian Jihad is a prequel novel to the classic sci-fi novel, Dune, written by Frank Herbert in the 1960s. This book, published in 2002 was written by Frank Herbert's son, Brian, and is co-authored by Kevin J. Anderson. It is the first novel if you read the books in chronological order, and it tells the story of events that were referred to in the original Dune Trilogy of novels.
This book (and the other two books in the trilogy) is set thousands of years before the events in the Dune novel (and movies). At the time, machines had enslaved humans on Earth and many planets that would eventually make up the guild. The machines were a combination of artificially intelligent thinking machines and cyborgs who used to be human but were able to preserve their brains in canisters that they could transfer from one mechanical body to the next. This book details the start of the war between humans and machines that was referenced in Dune and also details the beginnings of the relationship between House Harkonnen and House Atreides.
The hardcover version of the book is a little over 600 pages. That consists of about 612 pages of the actual story and then a character glossary that is about another 20 pages that gives a short explanation of the characters in the book. The story is very good but can be a bit hard to follow at times. The story jumps around from planet to planet, and shifts from the point of view of one character to another. Since there are a ton of characters in the book until you can keep straight who everyone is, it can get confusing. As you get deeper into the book, the story really focuses on just a handful of characters and the story is easier to digest. I have not read the original Dune trilogy yet (as of this writing) as I am reading the books in chronological order. So, I cannot say how this book compares to those written by Frank Herbert, but, it is a very well-written story that blends action, suspense, and drama. If you are a fan of the Dune movies or even just Sci-Fi books, movies, or TV series, this is worth the time to read.
