This book is about the children of Paul Atreides, Maud'Dib, but many of the old characters are back and are very welcome. There is a lot of mysticism and philosophy that surround the story.
The Children of Paul Atreides find themselves players in a game of intergalactic intrigue being played by all the major players in the Dune universe. This is a good read and it's the end of the first trilogy of Dune books.
Ranging from palace intrigue and desert chases to religious speculation and confrontations with the supreme intelligence of the universe, there is something here for all science fiction fans.
I love the Dune Chronicles. They seem to encompasse so much - from political theory to philosophy to family allegiance. Each book is immensely complex.
Great series. This book is not as strong as the first but make sure that you read it and Messiah so that you can get to the stunning fourth book - God Emperor of Dune.
