Query: Rabid Dune fans only, please

This book is worthwhile only in the context of its sire, the immortal _Dune_ and the other lesser volumes in *Frank* Herbert's original series. Read all those volumes before devoting time and money to this pale shadow of the original. The style is weak and the characterization is shallow. The plot is interesting only to the extent that it makes interesting speculations about the historical background of the original.
