First Lensman

Once they spent time explaining how obviously women couldn't have a Lens
and started using descriptions like “The men of the Galactic Patrol were widely known to be men”, I started having trouble continuing to read it.
So while I want to read the series because it is famous in the history of SF, I can only read one a year.

The best part was when our hero was on Pluto trying to talk to a truly alien being.
The author portrayed the alien as 4 dimensional and how it kept changing shape and color.
This was very interesting specially given that most aliens look a lot like humans or very nearly human.

I think I will go off to read a Danny Dunn book to clear my head.
