Sirius is a lovely book - certainly the best intro to Stapledon's works. I remember reading it when i was completely broke and freezing cold in Edinburgh in winter of 1972, and it warmed me up!
I read Sirius and Odd John due to Freeman Dyson advocating for Stapledon [0] but was underwhelmed by both.
Olaf Stapledon is the most underrated sci-fi author of all time
One of the most beautiful s.f. books of all times.
love olaf stapledon's work. starmaker is my all time favorite book <3
