"Nearly every story in You Know You Want This has someone getting stabbed, strangled, slashed, gouged, degloved, immolated, bludgeoned, bled out, brain-injured, or asswhupped."

"I suspect Roupenian knew 'Cat Person' would jaundice readers’ expectations one way or another, and she exploited this by opening the collection with 'Bad Boy,' a title that might suggest another misogynist miscreant. The couple who narrate the story torment their friend, a sad-sack guy fresh off a breakup who’s crashing on their couch. They tease him by having noisy sex in the next room; when they realize that degrading him turns them on, they coerce him into a ménage à trois full of 'pain and bruises, chains and toys,' escalating to a frenzy of deadly transgression... [The stories] all play off the same Nietzschean character archetypes: the weak dominated by the strong, victim versus victor. The victims are sensitive, passive introverts, forever in their own heads, wavering between reluctance and compliance. The victors, meanwhile, look just like you and me: Their innocent, kind, or seductive facades conceal a poisonous nature, like the appetizing rainbow slick of petroleum coating a dead ocean. The victim compounds their own suffering by over-empathizing with their tormentor, who is only emboldened by shows of vulnerability...."

From "Kristen Roupenian’s Power Dynamics/In her new book, the author of 'Cat Person' tells stories of sadism, narcissism, and gore" (The New Republic).

(I'm assuming you remember all the interest in the story "Cat Person." If you don't click on the tag.)
