Korede is bitter. How could she not be?

Her sister, Ayoola, is many things: the favorite child, the beautiful one, possibly sociopath. 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. Sharp as nails and full of deadpan wit, Oyinkan Braithwaite has written a deliciously deadly debut that’s as fun as it is frightening.

My Thoughts

My Sister, The Serial Killer is a book I’d describe as a chick lit/murder club book. Only thing is some members of this murder club are more reluctant than others. Korede is the ultimate big sister, something of a control freak, Korede is obsessed with cleaning and also ready to drop anything to come to her sister’s aid. These character traits are important as her sister, Ayoola, has a peculiar knack for murder.

Ayoola reminds me of the younger sister on Skinny Girl In Transit (can’t remember her name). She’s described as distractingly beautiful, self-absorbed with an undiagnosed psychosis. The fact that Korede has to literally clean up after her isn’t so bad since the mess is in Ayoola’s life and Korede has carefully constructed her life as a nurse in a thriving hospital who has a mild crush on her colleague. Unfortunately, there would be no story if Ayoola doesn’t find her way into this bubble.

I know it sounds terrible, but my favourite character is Ayoola. She’s a pathological liar, possibly a sociopath, definitely a serial killer but the way she lets the aftermath of her actions wash over her had me cackling. Like, who murders their boyfriend then goes ahead and start the awareness hashtag for his disappearance?

While Korede seems to be the more stable of the two, she’s actually more wicked in my opinion. She doesn’t have a mental psychosis to hide behind, she knows exactly what she’s doing and will do again. There is absolutely nothing that will come between her and Ayoola, no human she’ll consider more important.

Herein lies the beauty of My Sister, The Serial Killer, It’s not so much about the crime or its consequences but about the bond between Korede and Ayoola even when it appears to observers (their mother included) that they have a major beef with each other.

I don’t know why this book was classified a “Satire” though, I would have gone with dark humor, in the way Black Mirror episodes are hilarious.

Audiobook Impressions

The narrator of this book did a fantastic job. I always have complaints when actors try to recreate a Nigerian accent. Many of whom end up doing a weird “African” accent with no bearing. Here, it felt like I was listening to a friend read me a book which is a long way of saying she nailed the accent.

I also enjoyed how she was able to bring the characters to life. Especially Ayoola. She really nailed that annoying voice of the self-absorbed Nigerian slay queen. Except this one kills people.


Love it. I’ll recommend the audiobook. It’s short and sweet and I never wanted it to stop for anything.


Update: Apparently, the narrator is Nigerian which explains a lot and is an indictment on my laziness to ask Google.
