I am still reading The Left Hand of Darkness. 
This book has used three words: phlegmatic, obdurate, pertincious.
I am a bit awed.
I hardly see these words used even once in novels, and this book not only uses them, it uses them all in one sentence. In one sentence.
It is awesome.
I have barely started. And this whole thing with the king putting red cement on a new building – uh, red like blood, yeah? – is also awesome, but I don’t really understand that yet.
That’s okay. It’s early days yet.

“They are anything but a phlegmatic people, yet they are obdurate, they are pertinacious, they finish plastering joints.”
You might want to correct your spelling for “pertinacious”–not pertincious.
