Peter F. Hamilton has once again brought us a captivating sci-fi story that will have you reading every free moment you can get. This is epic world building at it's best; the scope of the universe covered in this book feels gigantic, and even better, completely believable.

Hamilton is one of the rare sci-fi authors who does try, and succeeds, at creating aliens that are very different from us. In this universe there are other species in the galaxy, but they do seem more on the rare side. The alien species that becomes the primary antagonist of the story is truly terrifying. They are the biological equivalent of the Borg, but they make the Borg look like your best friend and neighbor.

There's plenty of other good stuff built into this story to contemplate and think about as well, such as the social implications of life extension therapies, the implication of re-life procedures that can bring the dead back into the world, the changes in how we explore and expand once wormholes are invented, and much more.

If there is one thing that might be a little frustrating with this book it is that some of the characters and story lines in the early portion made me feel like they didn't belong. It isn't until the end of the book that some of this comes together and starts to make more sense.

My overall opinion though is if you love science fiction, this is a must read book. I look forward to reading the conclusion in 'Judas Unchained.'
