My Sister the Serial Killer by Oyinkan Braithwaite has been on my radar since its release – the title alone was enough to draw my attention. The concept sounded like a quirky thriller – I mean, how many books have you read that are about a character who reluctantly helps her sister get away with murder? Since this is such a short book, I’m going to keep my review short.
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.
A kind, handsome doctor at the hospital where Korede works, is the bright spot in her life. She dreams of the day when he will realize they’re perfect for each other. But one day Ayoola shows up to the hospital uninvited and he takes notice. When he asks Korede for Ayoola’s phone number, she must reckon with what her sister has become and what she will do about it.
The two sisters at the heart of this book were Ayoola and Korede. Ayoola had a pattern of murdering her boyfriends and expecting Korede to help her clean up afterwards. They had the classic ugly duckling dynamic: Ayoola was a beautiful woman who drew attention of men wherever she went, while Korede lurked in the shadows and lusted after her sister’s popularity. Her jealousy towards her sister peaked when Ayoola turned her attention to Korede’s long term crush.
This was one of those books that was really ruined by the ending. I was waiting for an ending that would truly finish Korede’s character growth and give Ayoola the karma she deserved, but it just didn’t happen. The ending didn’t provide the characters the opportunity for character growth or development – they were essentially the same characters as they were at the start. It was heartbreaking to see Korede stay in her sister’s shadow and be steamrolled by her once again.
A bad ending, lack of character growth, and really no sense of plot, My Sister the Serial Killer was riddled with issues and honestly not worth the read. The plot felt pointless, there was no good character growth, and the ending was super disappointing. It’s too bad that this book fell short, it had a great concept and interesting characters. If you’re looking for a good thriller, check out Gone Girl or And Then There Were None. 2/5
