The world has forgotten Onyesonwu. As a teen, Najeeba learned to become the beast of wind, fire and dust: the kponyungo. When that took too much from her, including the life of her father, she let it all go, and for a time, she was happy -- until only a few years later, when the small, normal life she'd built was violently destroyed. Now in her forties and years beyond the death of her second husband, Najeeba has just lost her beloved daughter. Onyesonwu saved the world. Najeeba knows this well, but the world does not. This is how the juju her daughter evoked works. One other person who remembers is Onyesonwu's teacher Aro, a harsh and hard-headed sorcerer. Najeeba has decided to ask him to teach her the Mystic Points, the powerful heart of sorcery. There is something awful Najeeba needs to kill and the Mystic Points are the only way. Najeeba is truly her daughter's mother.When Aro agrees to help, Najeeba is at last ready to forge her future. But first, she must confront her past -- for certain memories cannot lie in unmarked graves.
