Hilda Hilst was a Brazillian author whose works often addressed the topic of insanity (perhaps because both of her parents suffered from mental illness when she was a child.) Although she died in 2004, this short novel was translated from Portuguese into English only in 2014. To see whether her unusually poetic "stream of consciousness" writing style is your "cup of tea", try reading the portion of the English translation which is (currently) available free from Bomb Magazine.
