This book, though for me revolutionary, has not received a lot of the recognition I believe it is worthy of. Firstly, it explores many factors now taken for granted in postmodern fiction, e.g. dislocation, divided selves and a sense of 'numbed' perception. Furthermore, like Frank Herbert and Douglas Adams he is able to weave these themes into the narrative, whilst still maintaining a sense of coherence.
He stays within the confines of the science-fiction genre, yet deals with complex and arbitrary issues which blend philosophy and a deep questioning of cultural values. Comparisons with H.G. Wells and John Wyndham are permissible, but it is his use of philosophy that makes me admire him as a great writer. I have yet to find a writer who has the ability to question so much, yet still maintain an aura of intelligibility.
Clearly, this book is a whirlwind trip and yet one worth taking since this is no ordinary author. He may have gained greater recognition for many of his other books, yet it is this book that gives so much to the reader without taking anything away. You may question what he describes to you, but you will not be able to question his ability to tell it to you.
