Foundation’s Edge by Isaac Asimov is the fourth book in the the Foundation novels. This is the only book in the series to win a Hugo award for best novel – it did so in 1983. This book is a pretty good Star Trek episode, but I don’t know if I’d give it a Hugo. Certainly it’s the best book in the series so far, and I did find myself caught up in a few parts, but… I don’t know, I have yet to find myself blown away by the Foundation series.
In this book you still have a conflict between the First and Second Foundations, but now a third player enters the arena: Gaia. I’m not going to give anything away, but basically you learn some interesting and deep information on the origins of humanity in the Foundation universe. In some ways it’s a little out there, but pretty cool.
I only have two more novels left in the series, three if you count the prelude. I’m curious to see how this thing ends.
