2,5/5. I don’t get the hype this book gets right now. This is a mediocre thriller at best. The writing is very casual, without being bad there is nothing good or beautiful about it. The characters are blank, the plot is going mostly nowhere and all that could have made it reach a higher level wasn’t well exploited. The sisters duo, the Nigeria setting, the inside view with the killer, all of it is not much present and poorly executed. For me this was a poor thriller that try to be original but for a reason or another failed while doing it.
