My Rating: 4/5


A short, darkly funny, hand grenade of a novel about a Nigerian woman whose younger sister has a very inconvenient habit of killing her boyfriends.

“Femi makes three, you know. Three and they label you a serial killer.”

Korede is bitter. How could she not be? Her sister, Ayoola, is many things: the favorite child, the beautiful one, possibly sociopathic. And now Ayoola’s third boyfriend in a row is dead.

Korede’s practicality is the sisters’ saving grace. She knows the best solutions for cleaning blood, the trunk of her car is big enough for a body, and she keeps Ayoola from posting pictures of her dinner to Instagram when she should be mourning her “missing” boyfriend. Not that she gets any credit.

Korede has long been in love with a kind, handsome doctor at the hospital where she works. She dreams of the day when he will realize that she’s exactly what he needs. But when he asks Korede for Ayoola’s phone number, she must reckon with what her sister has become and how far she’s willing to go to protect her.

Sharp as nails and full of deadpan wit, Oyinkan Braithwaite’s deliciously deadly debut is as fun as it is frightening.

Ayoola and Korede are sisters. Ayoola is the beautiful sister, and has always been the favorite. She also has a history of her boyfriends dying while they are with her. Korede is the responsible sister that’s always there to help Ayoola. Korede wants some of the positive attention her sister always seems to get. Korede especially wants a doctor she works with to notice her. Unfortunately, the doctor is more interested in Ayoola than Korede.

Told from Korede’s point of view, this is a darkly humorous book about sisters. Korede is smart and practical. She has always looked out for her sister Ayoola, and continues to do that in spite of her sister’s killer tendencies. Ayoola is used to having everyone love her and always getting her way. On the rare occasion when things do not go her way, it does not end well.

This is not a mystery or thriller. It’s satirical contemporary fiction, where one of the characters happens to be a sociopathic serial killer. Mostly, this book is about the relationship between the sisters. Dark, disturbing, and complex.
