Most of the political relevance in this series comes from Jack. He thinks Santa is an elf-enslaving capitalist fat-cat, and I respect that. I still can't stop myself from cracking up whenever he calls Morrigan capitalist scum.
But I'm in the middle of a Hollowpox re-read, and I noticed that in the chapter De Flimsé, Morrigan plays a game called Tax Collector and "particularly enjoys the part where you burn down people's houses if they don't pay their taxes". Based.
And then the majority of Nevermoor's based-ness comes from the parallels that Hollowpox portrays in real life. Hollowpox = COVID-19. Oppressed Wunimals = Oppressed Asians. Tragic Hate Crimes by Humans = Tragic Hate Crimes by White People. Seriously, I never realised this series was so left-wing. I have a new-found respect for Jessica Townsend.
