I have to admit that I was disappointed with Children of Dune. It isn't the worst science fiction book I've read, but it isn't the best either. In my opinion Children of Dune is a mediocre science fiction book.
Children of Dune is a bit weak when compared to the first book, which is excellent in almost every possible way. I have to say that I don't understand how some people can praise this book, because I found it quite boring.
I can give this book only three stars, because I don't like it very much.
