The Blurb

“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.

The Review

Some books can completely grab you by the title alone. That was the way I felt about Oyinkan Braithwaite’s debut My Sister, the Serial Killer.

It is a story that focuses on the sisterly relationship between Korede and Ayoola. Their relationship, like most relationships between sisters, is complex. Ayoola seems to have it all – the good looks, the seemingly easy existence, and any man that she wants. Korede’s life is almost the antithesis. She works hard, gets less respect from home and she is in love with a colleague. On the side of all of this she has to help her sister clean up the messes that she has made because Ayoola can’t seem to help herself from killing the men she dates.

My Sister, the Serial Killer is dark and macabre but so glib and witty that I read it in one sitting. I chuckled through it all and then, rather worryingly, found the story relatable. Not in the sense of murder but in the sense that my sister and I grew up with pacts like this. For example, if one of use found it hard to conceive a child the other would do it for them, so the closeness of the sisters in such dark and dramatic circumstances was acutely relevant for me and my sister.

I really enjoyed reading My Sister, the Serial Killer and it absolutely any and all of the praise that is showered upon it and its author, Oyinkan Braithwaite.

My Sister, the Serial Killer by Oyinkan Braithwaite is available now.
