This is amazingly written and dense with detail. It stretches the mind and imagination to the breaking point. What is real? Who are we really? What are we? Where are we? Don't read this if you have strong convictions about your place in the universe for they will be challenged. But if you like mind-stretching epochs that melt away your own fantasies about life, this is a fantastic read. I loved it. But then again, I am a bit of a Ronan philosopher. John
