My Sister, the Serial Killer, Book Review and Summary

My Sister, the Serial Killer by author Oyinkan Braithwaite

Spoiler Free Review

My Sister, the Serial Killer is the story of two sisters in Nigeria who have more secrets than they should be able to handle. Lucky for them they’ve both become incredible liars.

Korede is a hard working, clean freak, nurse. Her sister Ayoola is basically the worst. She’s vain, selfish, manipulative, lazy, and just generally uses and abuses everyone around her. Korede puts up with out of obligation to family and protects her WAY more than she should.

The book opens with Korede helping Ayoola clean up the murder of her boyfriend. They move the body and clean up all of the evidence. Both of them seem weirdly calm about the whole scenario.

We find out early in the novel that Ayoola has now killed 3 of her boyfriends in this same manner. In “self-defense” with a knife that she got from their now deceased father.

3 murders, that officially makes Ayoola a serial killer.

The rest of the book follows the sisters as they navigate through hiding their secrets and creating new ones. They go through waves of nearly getting caught, getting themselves out of it, and then nearly getting caught again.

Korede is smart, organized, disciplined, and above all else loyal. It is only by these attributes that Ayoola is able to not get caught. However, she is gorgeous enough to probably get herself off of the hook were she to ever actually get arrested.

The book is mostly about their relationship as sisters. Korede is always at least a little jealous of how easy everything is for her beautiful sister. Ayoola is basically just out to prove that all men are dogs and deserve what she’s about to give them.

Their relationship rings true to me, at least to a certain extent. I do not have a sister so I can’t say how low I would go for mine. I do have a brother and I truly believe I would help him dispose of a body under the right circumstances. The main difference is that he doesn’t treat me like garbage.

Ayoola uses and abuses Korede just as much as she does anybody else. I do not understand why Korede continues to put up with it year after year. I get that blood is thicker than water but not if they wouldn’t do the same for you!

Regardless of how terrible Ayoola is to every single person in her life Korede maintains the role of big sister. At a certain point I began to lose respect for her loyalty.

My Sister, the Serial Killer is a very quick read. It’s just over 200 pages and has very short chapters so you’ll fly right through the drama filled pages. If you’re looking for a quick read to get you out of a slump this would be a good choice.

Update: since originally writing this book review the novel has been picked up to be adapted into a film. It’s currently listed as in development.
