I bought this book as it kept cropping up on my Facebook feed. I read it right the way through which (in all honesty) is more than I have done with some e-books I've bought recently.

But...

Goodies that turn out to be baddies and a rather one-dimensional villain are rather standard in many books. And although the ideas and concepts presented were rather thought-provoking, I originally encountered them in sci-fi over thirty years ago.

Not a bad book really,,, but not great. Sorry.
