Today, I made it through the Kralizec and finished the last book of the great Dune saga, Sandworms of Dune.
After rereading the 6 original books, I decided to travel back in time and first read the Prelude, Legends and Schools of Dune trilogies.
I always found the ending of Chapterhouse a bit unsatisfying, not a real closure. With the 2 sequels Hunters and Sandworms of Dune at least the story continued and the whole saga of Dune comes more to a closure. Maybe not the strongest but at least without open ends.
I would also recommend to read the Legends and maybe the Schools of Dune trilogies before the 2 final books. According to my opinion it provides you the necessary insight on the history of the enemy(ies) and various factions involved.
And now I finished it, will once again go back in time to dive into the Caladan trilogy.
