I’m about to finish the book Paul of Dune. It was after a comment from @Joanna Nanette (in some previous post) that i decided to go for this book after completing the Legends of dune and Prelude to dune trilogies.
Sofar, i find it a good book which contains several time periods in the life of Paul. The assassin wars in the young years of Paul were intriguing and fun to read.
I also found the period that covers the time between the dune and messiah books an addition to the whole story, as it shows a bit more about Paul’s struggle in becoming a tyrant. It also contains a massive assassin attempt which could certainly be added in the next movie.
