Mia sorella è una serial killer
📘 About This Book
When a meticulous Nigerian nurse is repeatedly forced to clean up the bloody messes left by her charismatic younger sister—who has a habit of killing her boyfriends—family loyalty is pushed to its absolute breaking point. The dark comedy and gripping tension reach a boiling point when the unpredictable killer sets her sights on the handsome doctor Korede has secretly loved for years.
📖 Summary
Set in Lagos, Nigeria, 'My Sister, the Serial Killer' follows Korede, a pragmatic and efficient nurse, whose life is constantly disrupted by her beautiful, sociopathic younger sister, Ayoola. The novel opens with a recurring crisis: Ayoola has once again killed a boyfriend, claiming self-defense. Korede, burdened by a deep-seated sense of familial duty and the mantra that 'family comes first,' arrives to scrub the crime scene with bleach, disposing of the evidence and protecting her sister from the consequences of her lethal impulses. While Korede excels at covering up these murders, she feels increasingly isolated, unable to confide in anyone about the bloody trail her sister leaves behind. The tension escalates when Ayoola begins dating Tade, a kind and handsome doctor at the hospital where Korede works—the very man Korede has long harbored a secret crush on. Faced with the realization that Tade may be the next victim, Korede must reconcile her unwavering loyalty to her sister with her growing moral crisis and personal feelings. As the narrative unfolds, Braithwaite explores the complex dynamics of the sisters' childhood, revealing the trauma inflicted by their abusive father, which shaped Ayoola’s detachment and Korede’s role as the perpetual protector. The book is a dark, razor-sharp satire that examines the nature of sisterhood, beauty standards, and the lengths to which people will go to preserve familial bonds. Through a blend of black comedy and suspense, Braithwaite questions whether blood is truly thicker than water, or if some loyalties are simply too destructive to maintain. The story moves at a blistering pace, offering a biting critique of social expectations while keeping the reader gripped by the sisters' toxic, unbreakable tether.
