"I am not angry. If anything, I am tired," Korede says, faced with yet another bloody crime scene to scour, yet another body to dump. The first few times, her beautiful sister Ayoola's self-defense claims seemed plausible, but the bodies have added up. And Korede Googled it: Three murders makes you a serial killer.

My Sister, the Serial Killer, the wry debut novel by Nigerian writer Oyinkan Braithwaite, tests the bonds of family, when family comes armed. The title says it all: Ayoola likes to kill her boyfriends. Korede can't quite bear to see her get caught: "Ayoola needs me; she needs me more than I need untainted hands." So, the gloves come on and the bleach comes out.

Ayoola is stunning, a "Bratz doll" next to her sister, who looks more like a "voodoo figurine." Men fall easy prey to her, while her looks make it impossible to for anyone to imagine she could be guilty of murder. If she went to trial, Korede thinks, she might be able to convince the court that her "actions were the fault of her victims and she had just acted as any reasonable, gorgeous person would."
