I'm having a very hard time remembering a story i read a while ago on wattpad. So i wanted to know if anyone know what is was called. The book is a about a black girl who was trained to be an assassin by her foster mom. Her foster mom dies so she takes over her foster moms job as an assassin. She starts dating a drug lord and he has lot of trouble staying loyal. There is like 3 books for the story. Does anyone know what this story is called?
