The first entry in a debut duology that displays the inventiveness of the works of Sarah Beth Durst, Marie Lu, and S. J. Kincaid. Kyra is the youngest Markswoman in the Order of Kali, a highly trained sisterhood of elite warriors armed with telepathic blades. Guided by a strict code of conduct, Kyra and the other Orders are sworn to protect the people of Asiana. But to be a Markswoman, an acolyte must repudiate her former life completely. Kyra has pledged to do so, yet she secretly harbours a fierce desire to avenge her dead family. When Kyra's beloved mentor dies in mysterious circumstances, and Tamsyn, the powerful, dangerous Mistress of Mental Arts, assumes control of the Order, Kyra is forced on the run.
