I love Stephenson - and this was another hit - absolutely loved it. The great thing about a good Stephenson book is it makes you think about the future in new ways, and this book was no exception.

It was really two books, and I certainly didn't see the second one coming. It starts out in modern times and then someone blows up the moon. We don't have time to find out who, as within a few years the fragments of the moon cause the worst asteriod shower earth has ever seen and wipe out all life in earth. We have time to send 1,500 people up into space - and this is their story.

The use of robots throughout the books was fascinating to me. Stephenson has clearly looked 10-20 years into our future and correctly predicted how it will go. From robot workers in space, nano-bots, nano-robot weapons, and more - we get a vivid portrayal of how robots might be a part of our future lives.

I thought the focus on use of whip technology in space was interesting. And of course, the whole notion of Cradle was just cool - though not sure about it's feasibility.
