I really loved this book and found myself thinking about it at odd times during my day. It's not often a book or story finds it way into my "real" life when I'm not actually reading. I was fascinated by the entire concept of a ship several thousand kilometers in length and width, a ship so large it could contain worlds inside of worlds and the endless possibilities that presented. The semi-immortal humans running things and taking care of the tourists on the ship left me a bit cold, but I think with warmer characters or family oriented leaders the entire concept would fail - leaders overrun with emotionality could not continue to function rationally after a 100,000 years of life. The action was fast and furious for almost all the book and the end came just as quickly. Very glad I read this book and I'm now looking for more from this author.
