She's an avid reader of Braille books, so she probably doesn't have one specific book she likes more than any other, but she strikes me as a gothic novels enthusiast. You know, stuff like Wuthering Heights

Zima is actually known for being surprisingly well read. Her fourth operator file bears a list of her recent reads, all of which being made-up for the universe. "Nikolamina", "Jump!", "The Death of Ilyich the Suspect" being a reference to the real world 'The Death of Ivan Ilyich', and "Friedrich's Theory of War". It's implied she has an interest in historical and classic literature, although I can't say for certain what genre the first two entries would be.

As a kid she was obsessed with a book about the red baron(ess), but she's embarrassed about it now so probably not that. Her room in s1 is shown with these two occult books, and her and sanyas room in s2 have whole shelves. Probably some occult book. Or a Sanya doujin. She has fantasies of medieval stuff (and there's cool promo art of it) so maybe she's into fantasy books. Hard to tell. I'll keep a look out during my next rewatch for books, as just grabbing those screenshots I noticed there are several named books in Ericas room that I hadn't noticed before.

SHE CAN'T READ
