First-time Nigerian author Oyinkan Braithwaite's novel My Sister, the Serial Killer, has been picked up by UK production companies Working Title and Big Talk for a film adaptation ahead of its release, reports Deadline.

Braithwaite, a graduate of Creative Writing and Law from Kingston University and a 2016 finalist for the Commonwealth Short Story Prize, received a five-figure advance from US-based publisher Doubleplay for her hghly-anticiapted debut.

The slasher comedy follows the dark shenanigans of sisters Korede and Ayoola. Korede finds herself in a predicament when she's forced to deal with Ayoola's peculiar habit of killing off the men she dates.

Here's a synopsis of the book via Deadline:

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. Sharp as nails and full of deadpan wit, Oyinkan Braithwaite has written a deliciously deadly debut that's as fun as it is frightening.

The book is set to be released Stateside on November 13, you can preorder it now on Amazon.

Braithwaite's success comes just after 24 year-old Nigerian-American novelist Tomi Adeyemi landed a lucrative deal with Fox Studios last year, ahead of the release for her debut Children of Blood and Bone.

African women writers are absolutely killing it and we couldn't be more delighted to follow their success!
