Its clear Mr. Herbert and Mr. Anderson are members of C.H.O.A.M. The two books Duke of Caladan and Lady of Caladan are 1 continuous story. Should have been a single book in my opinion, authors love to break up books lately it seems to "maximize profits" . As good members of the C.H.O.A.M directorship they are doing well.
The story in enjoyable. If your a Dune fan. You must be because your here. Its another book in the universe that we all enjoy.
