Just finished it late last night and I loved it. Amazing writing! Started it because I liked the movie Arrival but stories are so much more. Awesome analysis of issues in all their aspects (Liking What You See: A Documentary, Hell Is the Absence of God), such details of math and physics concepts (Division by Zero, Story of Your Life), language meaning (Seventy-Two Letters), all wrapped in great stories. Reminded me at times of Philip K.Dick.
