My Sister, The Serial Killer - Oyinkan Braithwaite

Satire meets slasher in this 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 favourite 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, the bright spot in her life, begins to fall for Ayoola. 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.

Oyinkan Braithwaite’s first novel is a smorgasbord of wit, genre-bending thrills and quiet melancholy.
