Query: A solid fourth installment in the Dune prequel series

The Butlerian Jihad is a very entertaining book, and that is why I gave it four stars. I still read books for the pure enjoyment of it, and discovering the ways in which Frank Herbert's son imagines(and hopefully researched) that the Dune Universe, the one that we all know from the origional Dune, came to be is about as enjoyable as most storylines I can envision. That said, this book is not incredibly well written. The character developement is the poorest of any book in the series so far, and the plot lines take on some awefull turns. The predictability gave way to a feeling of a massproduced science-fiction story that was released more to make money than to pay tribute to the world of Dune. If you are looking for a litterary masterpiece, move on, but if you are looking for a highly entertaining read that is near impossible to put down (no matter how predictable it sometimes can be) look no further.
