It's a book called Les Guerriers de l'Hiver (Winter Warriors) by Olivier Norek who was a cop before he started writing fiction.
Apparently his first book was ok. It was about humanising migrants who were stuck at the French border, so I guess he's not a literal racist but rather "rabid liberal sides with nazis when talking WW2"
Nonetheless the book is just glorifying the Finnish and depicting Soviets (well, he calls them "Russians" all the time lmao) as a zombie horde. It's all about how the "White Death" guy was a hero. I randomly opened a page and I kid you not first thing I read was "-Will we be free after that?" "-Well as free as one can be in Russia" 
Very cool mister anti-racism cop, and thank you to my fellow social democrats for thinking I wanted to read the most clownish anti-soviet propaganda by some lib who's got zero background in History
If you’re assuming I’m Amerikkkan you’re right. My fucking aunt claims to be a communist and simultaneously has been convinced purely emotionally (by her own admission) by anti-communist novels to hate actually existing socialism.
Hegemonic privilege means their viewpoint gets to be the default. Lurid stories about stalin shooting random musicians require actual work to undo, otherwise they live in all our hearts
So, a Trot?
Not even. Doomer Christian ish pacificist anarchist commun[e]ist.
