I like this book, but found the ending anticlimactic. The plot development got a little choppy, with all the flashbacks and flash-forwards. The storyline itself wasn't hard to follow, developing nicely with the characters.

I can't really put this book into the "Hard" Science Fiction category. I had a couple of moments of "suspension of disbelief". Logic holes are never good in Hard SciFi. And there was a bit too much of the Black Box technique, whereby we are forced to just accept without explanation that this thing works.

Hence, the two stars. I might be a touch stingy with my star ratings. I looked over my first wave of books, and found that everything was at least four stars. I did like this book, but I'm getting cranky as I use this website more and more.
