Nigerian author Oyinkan Braithwaite’s debut novel hasn’t even been released yet and has a film deal.

UK production company Working Title has optioned the book, according to Deadline, and will produce it with Big Talk’s Nira Park and Rachael Prior.

Here’s a synopsis for slasher satire/dark comedy novel: 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.

Big Talk and Working Title recently worked together on Baby Driver and the film The Kid Who Would Be King is in production.

This situation is a common one as of recent, and similar to Tomi Adeyemi’s Children of Blood and Bone, which was acquired by Fox 2000 before its release in a blockbuster deal. That book, which is a West African fantasy described as Avatar: The Last Airbender-meets-Black Lives Matter, just recently hit shelves.
