My Sister, The Serial Killer

Oyinkan Braithwaite

Kayleigh's Thoughts

Oyinkan Braithwaite’s My Sister, the Serial Killer is a sharp, darkly comedic novel centered on two Nigerian sisters: Korede, the responsible one, and Ayoola, the beautiful, charming one—who also happens to keep murdering her boyfriends. With its satirical tone, brisk pacing, and biting social commentary, the book explores themes of family loyalty, justice, and the psychological effects of generational dysfunction. 

Though undeniably entertaining, the novel’s brevity limits emotional depth. The bird’s-eye narration style offers an intentionally detached tone that fits the story’s wry voice but may leave some readers wanting a more immersive emotional experience. While it succeeds in offering a unique premise and sharp storytelling, it may feel underdeveloped for readers who prefer deeper emotional engagement.

I wanted to feel the tension between the sisters, but the emotional detachment kept me at arm’s length.
