Somewhat frightening, less fascinating.
I highly regard author's sharp observations and perspectives, but the ingenious creations (e.g. sharer, Pyro addicts) appear rudiments, yet fleshed out and better formed or made believe. I'd be a follower of Earthseed if it were not proclaimed as a Religion. Its poetic allure faded when I merely halfway through the book. It's Gospel verse without music, singing rendition is the key to deliver otherwise a dull text message. Realism feel in a sci-fi novel should not limit an imagination to be less.
