Like so many people, I enjoyed the first 2/3rds of this book. I wouldn't say I loved it, for I'm not particularly attached to hard-edged sci-fi like Seveneves. I found the story fascinating and did learn some things about orbital mechanics, but it did drone on and on and I found myself begging for the abridged version more than once.

Once I hit the turning point around the 2/3rd mark, any connection I had with the story that was pulling me along was suddenly gone. I tried for another 50 pages or so to keep it up, but my interest had vanished. This one is a did-not-finish.
