50 best sci-fi books of all time (surprisingly good list)

This list of 50 science fiction books includes The Echo Wife, Mary Robinette Kowal's The Calculating Stars, John Scalzi's Redshirts, Neal Stephenson's Snow Crash, and Carl Sagan's Contact. Entries describe plots and themes, such as Adina Giorno's alien reporting in Beautyland and Enoch Wallace's intergalactic rest stop in Clifford D. Simak's Way Station. Other titles include Sea of Rust by C. Robert Cargill, Fredric Brown's What Mad Universe, and Nnedi Okorafor's prequel to Who Fears Death. The excerpt cuts off partway through the list.
