My Sister the Serial Killer by Oyinkan Braithwaite is based in Nigeria, in the city Lagos. For black literature month I picked up this excellently written book that has been on my tbr for much too long. Braithwaite lets you experience a bit of their culture throughout this book. She is a bit vague about describing the place, but she is not afraid to put in cultural phrases for friends, aunts, family that we do not use. You get to have a feel about how the family regards relationships and duties based on age. You also get to see how the police are viewed and operated compared to how we are used to them working.

Braithwaite’s writing is sharp and concise — it really brings you into the book and holds you down. Braithwaite is also a poet, and she uses her poetry to influence how she styles the way she writes her novel. Using dense wording and her incisive choices of words you really get a sense of who she is as an author.
