I loved Cloud Cuckoo, I really didn’t care for Seveneves (and I actively disliked Termination Shock… it’s been a progression but I do believe my taste and Neal Stephenson have finally cleanly diverged), and Ioved The Overstory, though yeah, I agree that I think it ultimately was drawn out. I read it while on a big plant, tree, fungus and mycorrhizal kick, reading lots of books on the possibility of plant sensation/communication/cognition.
