I do need to dig in to Foundation. That's for sure. And read the books of The Expanse.
It's a bit of a new genre for me, so I am gingerly dipping my toes in here and there, and seeing how the water feels in different areas.
Earth Abides was such a brain-bending pleasure for me, that I think my expectations may be a tad overblown.
It is possible that - at the time (1959) - Canticle was far more ground-breaking than it is today. I also got some more perspective on it from reading about the author, and his personal revelations he experienced writing it. It is a very personal story for him, and he didn't even realize what he was processing by writing it.
(BTW - No shade for recommending it. I appreciate it, and am glad I read it! I just posted here instead of a private email to you, to open up the conversation to other interesting Hubskites.)
