If you're looking for very quick reads, I recommend Patricia Highsmith's Little Tales of Misogyny. I used to have the pictured edition, which was pocket-sized, a bit like The Little Book of Calm. Highsmith was a crime writer known for her dark and cynical, psychological crime stories.
Little Tales of Misogyny is a collection of very short pieces (some just a page, depending on the edition) satirising sexist stereotypes of the era. Stories have titles like "The Breeder", "The Victim", "The Fully Licensed Whore, or, the Wife", and "The Mobile-Bed Object". The stories show Highsmith's humour at its very blackest and cruellest. The tone will probably be too grim for some, and it's far
from being a feminist work.
Here, Graham Greene sells it better than me:
"With an eerie simplicity of style, Highsmith turns our next-door neighbors into sadistic psychopaths, lying in wait among white picket fences and manicured lawns. In the darkly satiric, often mordantly hilarious sketches that make up Little Tales of Misogyny, Highsmith upsets our conventional notions of female character, revealing the devastating power of these once familiar creatures "The Dancer," "The Female Novelist," "The Prude" who destroy both themselves and the men around them."
