I pretty much know what I am getting into with KSR novels. This one was about a massive generation ship and the issues they face seven generations in when it turns out the planetary system they are aiming for isn’t what they’d hoped. I guess for people who are more familiar with it, they see it as a long novel about why generation ships as a concept won’t work. This book is basically three novels in one. To my read, they don’t cohere so well and the one in the middle is mostly a stream-of-consciousness from an AI which I could have done without. The book has an odd ending, not really where you think it will go, but it’s still good reading.
