When Heaven Fell

When Heaven Fell is both interesting and depressing. The book is dark, showing a future that we wouldn't wish for. A cybernetic Master Race has conquered Earth, killing billions in the process. Humanity is now a subjugated race, basically a slave race, and it seems that is the way it will be forever. But life goes on and isn't too bad for some ... if you can adapt and accept your place. There is a lot of explicit sex, some fighting (the main protagonist is a soldier), and a bit of intrigue. Some deep moral questions are at least asked if not answered. (Would you betray those close to you to save your country? Your race?)
When Heaven Fell is a well written book. As trends in SF go, it was before its time.
It was a good read and I will be buying more of Barton's work.
