"An order of magical-knife wielding female assassins brings both peace and chaos to their post-apocalyptic world in this bewitching blend of science fiction and epic fantasy--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 harbors 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. Using one of the strange Transport Hubs that are remnants of Asiana's long-lost past, she finds herself in the unforgiving wilderness of desert that is home to the Order of Khur, the only Order composed of men. Among them is Rustan, a young, disillusioned Marksman whom she soon befriends. Kyra is certain that Tamsyn committed murder in a twisted bid for power, but she has no proof. And if she fails to find it, fails in her quest to keep her beloved Order from following Tamsyn down a dark path, it could spell the beginning of the end for Kyra--and for Asiana. But what she doesn't realize is that the line between justice and vengeance is razor thin. thin as the blade of a knife"-- Provided by publisher.
