I highly recommend "The Maker of Dune", if you can find a copy of the book somewhere.

"The Maker of Dune" adds a lot of personal insight to his work.

I used to have a copy but sold it at some point. Apparently it's hard to find now, given the very high price.

Update: The entire book is in the Internet Archive!
