After going to the trouble of importing a copy of this book from America through Amazon Marektplace (as it seems to be hard to obtain outside of the US), I was rather disappointed - and perhaps a little clearer as to why it's not readily available in the UK!
This book contains a series of dreams of imaginary worlds with a very different conception of time. Each chapter then is a thought experiment - but what I would have liked to see is some theme or character or reason why I should be carried through the thought experiments. There was no binding theme, and thus the book could better have been reduced to a list: Imagine a world where time is like X, Imagine a world where time is like Y and so on.
Maybe a poem on time would have been better than a whole book here.
It was not totally uninteresting, but neither did I feel it greatly profound. reading about Einstein in depth makes you more aware of the profound nature of time. reading popular physics books like "The Elegant Universe" likewise.
