hi anon, thanks for reading! i wrote F2C while deeply enamored/invested in reading Foucault, Deleuze, etc., which is probably obvious. certainly check out those like, "classics" if you haven't yet, as well as texts analyzing them. I assume, though, that when you ask for antipsych books, you're mostly interested in books that explicitly orbit critical Mad studies, and since this is my area of academic specialization :3

Liat Ben-Moshe, "Decarcerating Disability" and "Disability Incarcerated"

La Marr Jurelle Bruce, How to Go Mad Without Losing Your Mind

Margaret Price, Mad at School

Remi Yergeau, Authoring Autism (more "critical autism studies", but absolutely vital writing on epistemic & rhetorical violence)

Eric Stanley, Atmospheres of Violence

Jennifer Kilty, Containing Madness: Gender and ‘Psy’ in Institutional Contexts (varied in quality fyi)

Bren LeFrançois et al, Mad Matters (this is like one of the OG mad studies books)

I'd also recommend checking out some edited collections - there's the Mad Scholars Anthology (which I'm in, lol) and the Routledge Handbook of Mad Studies, both of which are varied in quality and relevance by virtue of being edited collections, but yeah, worth a skim to find the good stuff.
