My Sister, the Serial Killer
Oyinkan Braithwaite · first published 2018 · ISBN 9780385544235
Korede is a nurse in Lagos with a secret: her sister Ayoola has killed three boyfriends, each time claiming self-defense. And each time, Korede has cleaned up the evidence. When Ayoola targets another man that Korede feels protective of, Korede's loyalty collides with her conscience. The story spirals backward through their past and forward into the question of how much you can forgive someone because they're family.

Braithwaite pulls off a rare feat: she makes a book about serial murder both darkly funny and psychologically acute. Korede's voice is sharp and confused at once. Her simultaneous love for and resentment toward her sister creates a moral texture that most thrillers never touch. It's a book about loyalty, complicity, and the cost of looking away.
