Robots and Empire

Robots and Empire takes place several hundred years after the last Robot book. The girl our hero was cheating with is still alive - spacers can live to be 3-400 years old. And of course R. Daneel Olivaw and R. Giskard are back as well. This book basically tries to tie together the "Robot" series with the "Foundation" series.

You see, in the latter, there are few robots at all (at least, as far as I can remember). So how did we get from a society with dozens if not hundreds of robots per human to one with NO robots? You have to read this book.

This one also introduces the Zeroeth law of Robotics. A robot himself comes up with this law.

Personally, I like it when and author ties disparate series together. I know is kind of retro-fitting things together, and it can feel forced at times, but I think it's a neat idea. I think I like this book the second most (with the first being the best).

This book also subverts the first law in an interesting way, by (sort of) re-defining what a human is. But you'll have to read it to find out exactly how. Personally, I wish he had explored that a little more and resolved it, rather than use it for a small section then abandon the idea.

8 out of 10.
