Weakest of the epic series. I have read and re-read the entire series numerous times over the past 20+ years. There are parts in the book, or should I say characters, that I absolutely love and I look forward to those Parts. However, by this time in the timeline Maya just becomes whiny and her mood swings just get annoying. There are Parts that just go on forever, weighed down in KSR’s attention to detail. This really is a great book and all sci-fi fans should read it. Even now, the political and social situations are relevant if only you replace the power countries of the 90s with those in play today. And with the current space race heating up and talk of colonization this book and the entire Martian series should be mandatory reading for those planning our future.
