Oyinkan Braithwaite's debut is a razor-sharp dark comedy that follows Korede, a nurse whose beautiful younger sister Ayoola has an unfortunate habit of killing her boyfriends. When Ayoola shows up with another corpse, Korede dutifully helps dispose of the evidence—until Ayoola sets her sights on Tade, the doctor Korede secretly loves.

This slim novel (under 250 pages) packs a punch with its pitch-black humor and unflinching examination of toxic family dynamics. Braithwaite excels at creating an unreliable narrator in Korede, whose devotion to her sister borders on pathological enablement.

The author's background as a creative writing graduate shows in her economical prose—every sentence serves a purpose, and the Lagos setting feels authentic without being overly explained. The book works best as a psychological study of sibling relationships and complicity.

Korede's internal struggle between moral duty and family loyalty creates genuine tension, especially as bodies pile up and her sister's behavior escalates. The dark humor lands consistently, making disturbing situations genuinely funny without undermining their horror.

However, readers expecting a traditional thriller may feel unsatisfied. The mystery isn't who's doing the killing—it's whether Korede will finally stand up to Ayoola. Some plot points feel underdeveloped, particularly the romantic subplot with Tade, which serves more as a catalyst than a fully realized relationship. The ending, while thematically appropriate, may leave some wanting more resolution. This book is perfect for readers who enjoyed 'Gone Girl' or 'Big Little Lies'—those who appreciate morally complex characters and domestic noir with bite. Fans of authors like Gillian Flynn or Tana French will find familiar territory here. Skip this if you prefer straightforward mysteries, dislike dark humor, or need sympathetic protagonists. The violence, while not graphic, is persistent, and the moral ambiguity runs deep. Braithwaite has crafted a memorable debut that announces her as a voice to watch in contemporary fiction.
