Seveneves   Neal Stephenson
Brilliant, fascinating, well-written, 800-plus page novel about the death of the earth because of the destruction of the moon and humanity’s attempt to survive over 5000 years. As much a dissertation on things like celestial mechanics, terra forming, and other highly technical subjects as fiction. Stephenson can write clearly, almost beautifully, about the most complicated topics. Loved many of the characters. Not quite as good as Anathem, my favorite of his, but up there near Cryptonomicon, which I also loved. Really enjoyed it.
