Reread with my book club 10/7/2023: I thought it was even better the second time around! 

Korede has just gotten another call from her little sister Ayoola - her third boyfriend has been stabbed to death in “self-defense.” So she heads over with her cleaning supplies and protects her sister. Korede agonizes over the deaths, feeling guilty but also unwilling to turn in Ayoola. But then her sister catches the eye of Korede’s boss, a kind doctor (and also Korede’s long-time crush). Family is everything, but Korede doesn’t want to witness yet another murder.

It’s deliciously sharp - with quick chapters bouncing from one scene to the next. Korede is struggling to maintain any form of control, and we flash between important memories as she struggles with that trauma.

The writing is clever and darkly funny. Korede’s inner dialogue is sarcastic and filled with slightly-absurd justifications.

Braithwaite plays with the different forms of societal hierarchy and power. Men have control - whether they’re perceptive & aware of the intricacies of the world or not. Ayoola has power because of her beauty; she sometimes wields this manipulatively and other times is ignorant to the way she affects others. 

But the most important theme in My Sister, the Serial Killer is, of course, family. Korede has been her sister’s keeper since the day she was born. She’s been tossed aside by her parents and gives way too much of herself to Ayoola, but she can’t help it. Ayoola is her responsibility, and she loves her, and she’d do anything to protect her.

There are questions here around family loyalty & sisterhood, on guilt & responsibility (enabling others), on beauty & social media, on men’s general lack of ability to listen & learn, on trauma & cycles of abuse (violence causing violence).

Original review February 2022:

A whirlwind of a book. Fast-paced, with some biting satire. Witty dark commentary on beauty, on family and sisterhood, on violence. I wanted it to be more - to be a bit longer and deeper and to dive into these characters more.
