unhinged women book suggestions?

hi all! looking to buy a gift for my partner based on books she has read previously:

- bunny by mona awad

- gone girl by gillian flynn

- bluets by maggie nelson

she likes stories about unhinged women, but she has also been getting more into thought-provoking/ethical works. she recently read:

- monster by naoki urasawa (manga)

- vegan feminist theory

sort of a weird ask, but would love to know if anyone has any recs. thank you!!
