It could be a good story
I have read a lot of the Dune books. When I saw this one for free, I was curious, so I got it.
A short story, it does have a lot of the Herbert's running themes, politics, genetic manipulation through breeding in humans, comments on "good" government vs "working" government, and so on.
It could be good, but there are too many editing errors to make it enjoyable. If you can overlook them, then I guess it is OK. I couldn't.
