I know everyone says it's good, etc. I just want to reinforce the point. It is really really good. Definitely one of the best scifi I have read. The story just gets bigger and bigger as the books progress as well as the imagined tech and physics. I know it's cliche but it definitely caused me to think slightly differently when looking up at a night sky.

Highly recommended. Sequel is quite good as well.

Great book, somewhat unusual sci fi.

Really, really good. I would rank it up in top scifi I've ever read.
